Configuration file format

In its basic form, aptitude's configuration file is a list of options and their values. Each line of the file should have the form “Option Value;”: for instance, the following line in the configuration file sets the option Aptitude::Theme to “Dselect”.

Aptitude::Theme "Dselect";

An option can “contain” other options if they are written in curly braces between the option and the semicolon following it, like this:

Aptitude::UI {
  Package-Status-Format "";
  Package-Display-Format "";
};

An option that contains other options is sometimes called a group. In fact, the double colons that appear in option names are actually a shorthand way of indicating containment: the option Aptitude::UI::Default-Grouping is contained in the group Aptitude::UI, which itself is contained in the group Aptitude. Thus, if you wanted to, you could set this option to "" as follows:

Aptitude {
  UI {
    Default-Grouping "";
  };
};

For more information on the format of the configuration file, see the manual page apt.conf(5).

Locations of configuration files

aptitude's configuration is read from the following sources, in order:

  1. The user's configuration file, ~/.aptitude/config. This file is overwritten when the user modifies settings in the Options menu.

  2. The system configuration file, /etc/apt/apt.conf.

  3. Default values stored in /usr/share/aptitude/aptitude-defaults.

  4. Default values built into aptitude.

When an option is being checked, these sources are searched in order, and the first one that provides a value for the option is used. For instance, setting an option in /etc/apt/apt.conf will override aptitude's defaults for that option, but will not override user settings in ~/.aptitude/config.

Available configuration options

The following configuration options are used by aptitude. Note that these are not the only available configuration options; options used by the underlying apt system are not listed here. See the manual pages apt(8) and apt.conf(5) for information on apt options.

Option: Apt::Install-Recommends
Default: true
Description: If this option is true and Aptitude::Auto-Install is true, then whenever you mark a package for installation, aptitude will also mark the packages it recommends for installation. Furthermore, if this option is true, aptitude will not consider packages to be unused (and thus will not automatically remove them) as long as any installed package reommends them. For more information, see the section called “Managing automatically installed packages”.
Option: Aptitude::Allow-Null-Upgrade
Default: false
Description: Normally, if you try to start an install run when no actions will be performed, aptitude will print a warning and return to the package list. If this option is true, aptitude will continue to the preview screen whenever there are upgradable packages, rather than displaying a reminder about the ActionsMark Upgradable (U) command.
Option: Aptitude::Always-Use-Safe-Resolver
Default: false
Description: If this option is true, aptitude's command-line actions will always use a “safe” dependency resolver, as if --safe-resolver had been passed on the command line.
Option: Aptitude::Autoclean-After-Update
Default: false
Description: If this option is true, aptitude will clean up obsolete files (see ActionsClean obsolete files) every time you update the package list.
Option: Aptitude::Auto-Install
Default: true
Description: If this option is true, aptitude will automatically attempt to fulfill the dependencies of a package when you select it for installation.
Option: Aptitude::Auto-Fix-Broken
Default: true
Description: If this option is false, aptitude will ask for permission before attempting to fix any broken packages.
Option: Aptitude::Auto-Upgrade
Default: false
Description: If this option is true, aptitude will automatically flag all upgradable packages for upgrade when the program starts, as if you had issued the command ActionsMark Upgradable (U).
Option: Aptitude::CmdLine::Always-Prompt
Default: false
Description: In command-line mode, if this is set, aptitude will always prompt before starting to install or remove packages, even if the prompt would normally be skipped. This is equivalent to the -P command-line option.
Option: Aptitude::CmdLine::Assume-Yes
Default: false
Description: In command-line mode, if this option is true, aptitude will act as if the user had answered “yes” to every prompt, causing most prompts to be skipped. This is equivalent to the -y command-line option.
Option: Aptitude::CmdLine::Download-Only
Default: false
Description: In command-line mode, if this option is true, aptitude will download package files but not install them. This is equivalent to the -d command-line option.
Option: Aptitude::CmdLine::Fix-Broken
Default: false
Description: In command-line mode, if this option is true, aptitude will be more aggressive when attempting to fix the dependencies of broken packages. This is equivalent to the -f command-line option.
Option: Aptitude::CmdLine::Ignore-Trust-Violations
Default: false
Description: In command-line mode, causes aptitude to ignore the installation of untrusted packages. This is a synonym for Apt::Get::AllowUnauthenticated.
Option: Aptitude::CmdLine::Package-Display-Format
Default: %c%a%M %p# - %d#
Description: This is a format string, as described in the section called “Customizing how packages are displayed”, which is used to display the results of a command-line search. This is equivalent to the -F command-line option.
Option: Aptitude::CmdLine::Package-Display-Width
Default:
Description: This option gives the width in characters for which command-line search results should be formatted. If it is empty (the default; ie, ""), search results will be formatted for the current terminal size, or for an 80-column display if the terminal size cannot be determined.
Option: Aptitude::CmdLine::Request-Strictness
Default: 10000
Description: When run in command-line mode, if dependency problems are encountered, aptitude will add this value to the problem resolver score of each action that you explicitly request.
Option: Aptitude::CmdLine::Resolver-Debug
Default: false
Description: In command-line mode, if this option is true, aptitude will print extremely verbose information while attempting to resolve broken dependencies. As the name suggests, this option is primarily meant to aid in debugging the problem resolver.
Option: Aptitude::CmdLine::Resolver-Dump
Default:
Description: In command-line mode, if it is necessary to resolve broken dependencies and this option is set to the name of a writable file, the resolver state will be dumped to this file before any calculations are undertaken.
Option: Aptitude::CmdLine::Resolver-Show-Steps
Default: false
Description: If this option is true, then a dependency solution will be displayed as a sequence of resolutions of individual dependencies; for instance, “wesnoth depends upon wesnoth-data (= 1.2.4-1) -> installing wesnoth-data 1.2.4-1 (unstable)”. To toggle between the two display modes, press o at the prompt “Accept this solution?”.
Option: Aptitude::CmdLine::Safe-Upgrade::No-New-Installs
Default: false
Description: In command-line mode, if this option is true, the safe-upgrade command will not attempt to resolve dependencies by installing new packages. If upgrading package A would require package B to be newly installed, package A will not be upgraded. This corresponds to the command-line option --no-new-installs.
Option: Aptitude::CmdLine::Show-Deps
Default: false
Description: In command-line mode, if this option is true, aptitude will display a brief summary of the dependencies (if any) relating to a package's state. This is equivalent to the -D command-line option.
Option: Aptitude::CmdLine::Show-Size-Changes
Default: false
Description: In command-line mode, if this option is true, aptitude will display the expected change in the amount of space used by each package. This is equivalent to the -Z command-line option.
Option: Aptitude::CmdLine::Show-Versions
Default: false
Description: In command-line mode, if this option is true, aptitude will display the version of a package that is being installed or removed. This is equivalent to the -V command-line option.
Option: Aptitude::CmdLine::Show-Why
Default: false
Description: In command-line mode, if this option is true, aptitude will display the manually installed packages that require each automatically installed package, or the manually installed packages that cause a conflict with each automatically removed package. This is equivalent to the -W command-line option and displays the same information you can access via aptitude why or by pressing i in a package list.
Option: Aptitude::Safe-Resolver::No-New-Installs
Default: false
Description: If this option is enabled, then when the “safe” dependency resolver has been activated via --safe-resolver, the resolver will not be allowed to install packages that are not currently installed. This is similar to Aptitude::CmdLine::Safe-Upgrade::No-New-Installs, but applies only to command-line actions other than safe-upgrade.
Option: Aptitude::Safe-Resolver::No-New-Upgrades
Default: false
Description: If this option is enabled, then when the “safe” dependency resolver has been activated via --safe-resolver, the resolver will not be allowed to resolve dependencies by upgrading packages.
Option: Aptitude::CmdLine::Simulate
Default: false
Description: This option is deprecated; use Aptitude::Simulate instead. In command-line mode, causes aptitude to just display the actions that would be performed (rather than actually performing them); in the visual interface, causes aptitude to start in read-only mode regardless of whether you are root or not. This is equivalent to the -s command-line option.
Option: Aptitude::CmdLine::Verbose
Default: 0
Description: This controls how verbose the command-line mode of aptitude is. Every occurrence of the -v command-line option adds 1 to this value.
Option: Aptitude::CmdLine::Visual-Preview
Default: false
Description: If this option is true, aptitude will enter its visual mode to display the preview of an installation run and to download packages.
Option: Aptitude::Debtags-Binary
Default: /usr/bin/debtags
Description: The absolute path to the debtags command. If configured with libept support, aptitude will invoke this program whenever the package lists are updated, passing it the arguments listed in Aptitude::Debtags-Update-Options.
Option: Aptitude::Debtags-Update-Options
Default: --local
Description: Additional options to pass to debtags update when invoking it after the package lists are updated. These are split at whitespace; single and double-quoted strings are recognized, so setting this to “--vocabulary='/file with a space” will store the debtags vocabulary in “/file with a space”.
Option: Aptitude::Delete-Unused
Default: true
Description: If this option is true, automatically installed packages which are no longer required will be automatically removed. For more information, see the section called “Managing automatically installed packages”.
Option: Aptitude::Delete-Unused-Pattern
Default:
Description: Deprecated alias for Aptitude::Keep-Unused-Pattern. If Aptitude::Keep-Unused-Pattern is unset or set to an empty string, the value of this configuration option will override it. Otherwise, Aptitude::Delete-Unused-Pattern is ignored.
Option: Aptitude::Display-Planned-Action
Default: true
Description: If this option is true, aptitude will display a preview screen before actually carrying out the actions you have requested.
Option: Aptitude::Forget-New-On-Install
Default: false
Description: If this option is true, aptitude will clear the list of new packages whenever you install, upgrade, or remove packages, as if you had issued the command ActionsForget new packages (f).
Option: Aptitude::Forget-New-On-Update
Default: false
Description: If this option is true, aptitude will clear the list of new packages whenever the package list is updated, as if you had issued the command ActionsForget new packages (f).
Option: Aptitude::Get-Root-Command
Default: su:/usr/bin/su
Description: This option sets the external command that aptitude will use to switch to the root user (see the section called “Becoming root). It has the form protocol:command. protocol must be either su or sudo; it determines how aptitude invokes the program when it wants to gain root privileges. If protocol is su, then command -c arguments is used to become root; otherwise, aptitude uses command arguments. The first word in command is the name of the program that should be invoked; remaining words are treated as arguments to that program.
Option: Aptitude::Ignore-Recommends-Important
Default: false
Description: In previous versions of aptitude, the setting Aptitude::Recommends-Important caused recommendations to be installed automatically, the same way that Apt::Install-Recommends does today. If this option is set to false and Aptitude::Recommends-Important is also set to false, aptitude will set Apt::Install-Recommends to false and set Aptitude::Ignore-Recommends-Important to true on startup.
Option: Aptitude::Ignore-Old-Tmp
Default: false
Description: Old versions of aptitude created a directory ~/.aptitude/.tmp which is no longer necessary. If the directory exists and Aptitude::Ignore-Old-Tmp is true, aptitude will ask you whether to remove this directory. This option is automatically set to true after you reply. On the other hand, if the directory does not exist, this option is set to false so that you will be notified if it reappears.
Option: Aptitude::Keep-Recommends
Default: false
Description: If this option is true, then aptitude will not consider packages to be unused (and thus will not automatically remove them) as long as any installed package recommends them, even if Apt::Install-Recommends is false. For more information, see the section called “Managing automatically installed packages”.
Option: Aptitude::Keep-Suggests
Default: false
Description: If this option is true, then aptitude will not consider packages to be unused (and thus will not automatically remove them) as long as any installed package suggests them. For more information, see the section called “Managing automatically installed packages”.
Option: Aptitude::Keep-Unused-Pattern
Default:
Description: If Aptitude::Delete-Unused is true, only unused packages which do not match this pattern (see the section called “Search Patterns”) will be removed. If this option is set to an empty string (the default), all unused packages will be removed.
Option: Aptitude::LockFile
Default: /var/lock/aptitude
Description: A file that will be fcntl-locked to ensure that at most one aptitude process can modify the cache at once. In normal circumstances, you should never need to modify this; it may be useful for debugging. Note: if aptitude complains that it cannot acquire a lock, this is not because the lock file needs to be deleted. fcntl locks are managed by the kernel and will be destroyed when the program holding them terminates; failure to acquire the lock means that another running program is using it!
Option: Aptitude::Log
Default: /var/log/aptitude
Description: If this is set to a nonempty string, aptitude will log the package installations, removals, and upgrades that it performs. If the value of Aptitude::Log begins with a pipe character (ie, “|”), the remainder of its value is used as the name of a command into which the log will be piped: for instance, |mail -s 'Aptitude install run' root will cause the log to be emailed to root. To log to multiple files or commands, you may set this option to a list of log targets.
Option: Aptitude::Parse-Description-Bullets
Default: true
Description: If this option is enabled, aptitude will attempt to automatically detect bulleted lists in package descriptions. This will generally improve how descriptions are displayed, but it is not entirely backwards-compatible; some descriptions might be formatted less attractively when this option is true than when it is false.
Option: Aptitude::Pkg-Display-Limit
Default:
Description: The default filter applied to the package list; see the section called “Search Patterns” for details about its format.
Option: Aptitude::ProblemResolver::Allow-Break-Holds
Default: false
Description: If this option is set to true, the problem resolver will consider breaking package holds or installing forbidden versions in order to resolve a dependency. If it is set to false, these actions will be rejected by default, although you can always enable them manually (see the section called “Solving Dependency Problems”).
Option: Aptitude::ProblemResolver::BreakHoldScore
Default: -300
Description: How much to reward or penalize solutions that change the state of a held package or install a forbidden version. Note that unless Aptitude::ProblemResolver::Allow-Break-Holds is set to true, the resolver will never break a hold or install a forbidden version unless it has explicit permission from the user.
Option: Aptitude::ProblemResolver::BrokenScore
Default: -100
Description: How much to reward or penalize prospective solutions based on the number of dependencies they break. For each dependency broken by a possible solution, this many points are added to its score; typically this should be a negative value.
Option: Aptitude::ProblemResolver::Discard-Null-Solution
Default: true
Description: If this option is true, aptitude will never suggest cancelling all of your proposed actions in order to resolve a dependency problem.
Option: Aptitude::ProblemResolver::EssentialRemoveScore
Default: -100000
Description: How much to reward or penalize solutions that remove an Essential package.
Option: Aptitude::ProblemResolver::ExtraScore
Default: -1
Description: Any version of a package whose Priority is “extra” will have this many points added to its score.
Option: Aptitude::ProblemResolver::FullReplacementScore
Default: 500
Description: Removing a package and installing another package that fully replaces it (i.e., conflicts with it, replaces it, and provides it) is assigned this score.
Option: Aptitude::ProblemResolver::ImportantScore
Default: 5
Description: Any version of a package whose Priority is “important” will have this many points added to its score.
Option: Aptitude::ProblemResolver::Infinity
Default: 1000000
Description: A “maximum” score for potential solutions. If a set of actions has a score worse than -Infinity, it will be discarded immediately.
Option: Aptitude::ProblemResolver::InstallScore
Default: -20
Description: How much weight the problem resolver should give to installing a package, if the package is not already going to be installed.
Option: Aptitude::ProblemResolver::KeepScore
Default: 0
Description: How much weight the problem resolver should give to keeping a package in its current state, if that package is not already going to be kept in its current state.
Option: Aptitude::ProblemResolver::Max-Successors
Default: 0
Description: When new possible solutions are being generated, this value controls how long the generation procedure lasts. Successors are generated in discrete bundles, and as soon as at least one and at most Max-Successors nodes have been generated, successor generation terminates. Turning this value up might cause the first few generated solutions to have higher scores; on the other hand, it might cause each resolver “step” to take a long time.
Option: Aptitude::ProblemResolver::NonDefaultScore
Default: -40
Description: How much weight the problem resolver should give to installing a non-default version of the package (one that is not the current version and not the “candidate version”).
Option: Aptitude::ProblemResolver::OptionalScore
Default: 1
Description: Any version of a package whose Priority is “optional” will have this many points added to its score.
Option: Aptitude::ProblemResolver::PreserveAutoScore
Default: 0
Description: How much weight the problem resolver should give to preserving automatic installations or removals.
Option: Aptitude::ProblemResolver::PreserveManualScore
Default: 60
Description: How much weight the problem resolver should give to preserving explicit user selections.
Option: Aptitude::ProblemResolver::RemoveScore
Default: -300
Description: How much weight the problem resolver should give to removing a package (if it is not already marked for removal).
Option: Aptitude::ProblemResolver::RequiredScore
Default: 4
Description: Any version of a package whose Priority is “required” will have this many points added to its score.
Option: Aptitude::ProblemResolver::ResolutionScore
Default: 50
Description: In addition to all other scoring factors, proposed solutions that actually resolve all unsatisfied dependencies are awarded this many extra points.
Option: Aptitude::ProblemResolver::StandardScore
Default: 3
Description: Any version of a package whose Priority is “standard” will have this many points added to its score.
Option: Aptitude::ProblemResolver::StepLimit
Default: 5000
Description: The maximum number of “steps” which should be performed by the problem resolver on each attempt to find a solution to a dependency problem. Decreasing this number will make aptitudegive up” sooner; increasing it will permit the search for a solution to consume much more time and memory before it is aborted. Setting StepLimit to 0 will disable the problem resolver entirely. The default value is large enough to accomodate commonly encountered situations, while preventing aptitude from “blowing up” if an overly complicated problem is encountered. (note: this applies only to command-line searches; in the visual interface, the resolver will continue working until it reaches a solution)
Option: Aptitude::ProblemResolver::StepScore
Default: 70
Description: How much to reward or penalize prospective solutions based on their length. For each action performed by a solution, this many points are added to its score. The larger this value is, the more the resolver tends to stick with its first choice rather than considering alternatives; this will cause it to produce a solution more quickly, but the solution might be of slightly lower quality than it would otherwise be.
Option: Aptitude::ProblemResolver::Trace-Directory
Default:
Description: If this value is set, then each time the problem resolver produces a solution, a stripped-down version of the package state sufficient to reproduce that solution is written to the given file. If Aptitude::ProblemResolver::Trace-File is also set, the same information will also be written to the trace file. Trace directories are more transparent than trace files, and are more suitable for, e.g., including in source trees as test cases.
Option: Aptitude::ProblemResolver::Trace-File
Default:
Description: If this value is set, then each time the problem resolver produces a solution, a stripped-down version of the package state sufficient to reproduce that solution is written to the given file. If Aptitude::ProblemResolver::Trace-Directory is also set, the same information will also be written to the trace directory. A trace file is simply a compressed archive of a trace directory; it will take less space than the trace directory and is suitable for transmission over a network.
Option: Aptitude::ProblemResolver::UndoFullReplacementScore
Default: -500
Description: Installing a package and removing another package that fully replaces it (i.e., conflicts with it, replaces it, and provides it) is assigned this score.
Option: Aptitude::ProblemResolver::UnfixedSoftScore
Default: -200
Description: How much to reward or penalize leaving a Recommends relationship unresolved. This should typically be less than RemoveScore, or aptitude will tend to remove packages rather than leaving their Recommendations unfixed. See the section called “Solving Dependency Problems” for details.
Option: Aptitude::ProblemResolver::UpgradeScore
Default: 0
Description: How much weight the problem resolver should give to upgrading (or downgrading) a package to its candidate version, if the package was not already going to be upgraded.
Option: Aptitude::ProblemResolver::WaitSteps
Default: 50
Description: The number of resolver steps to perform in the foreground before moving the resolution to the background thread. aptitude will be unresponsive while this computation takes place; decreasing this value will make the program more responsive, but may cause the progress indicator to appear unnecessarily.
Option: Aptitude::Purge-Unused
Default: false
Description: If this option is true and Aptitude::Delete-Unused is also true, then packages which are unused will be purged from the system, removing their configuration files and perhaps other important data. For more information about which packages are considered to be “unused”, see the section called “Managing automatically installed packages”. THIS OPTION CAN CAUSE DATA LOSS! DO NOT ENABLE IT UNLESS YOU KNOW WHAT YOU ARE DOING!
Option: Aptitude::Recommends-Important
Default: true
Description: This is an obsolete configuration option that has been superseded by Apt::Install-Recommends. On startup, aptitude will copy Aptitude::Recommends-Important (if it exists) to Apt::Install-Recommends and then clear Aptitude::Recommends-Important in your user configuration file.
Option: Aptitude::Sections::Top-Sections
Default: "main"; "contrib"; "non-free"; "non-US";
Description: A configuration group whose elements are the names of the top-level archive sections. The “topdir”, “subdir”, and “subdirs” grouping policies use this list to interpret Section fields: if the first path element of a package's Section is not contained in this list, or if its Section has only one element, then the package will be grouped using the first member of this list as its first path element. For example, if the first member of Top-Sections is “main”, then a package whose Section is “games” will be treated as if its Section field were “games/arcade”.
Option: Aptitude::Sections::Descriptions
Default: See $prefix/share/aptitude/section-descriptions
Description: This option is a group whose members define the descriptions displayed for each section when using the “section” package hierarchy grouping policy. Descriptions are assigned to section trees based on the last component of the name: for instance, a member of this group named “games” will be used to describe the Sections “games”, “non-free/games”, and “non-free/desktop/games”. Within the text of section descriptions, the string “\n” will be replaced by a line-break, and the string “''” will be replaced by a double-quote character.
Option: Aptitude::Simulate
Default: false
Description: In command-line mode, causes aptitude to just display the actions that would be performed (rather than actually performing them); in the visual interface, causes aptitude to start in read-only mode regardless of whether you are root or not. This is equivalent to the -s command-line option.
Option: Aptitude::Spin-Interval
Default: 500
Description: The number of milliseconds to delay in between updating the “spinner” that appears while the problem resolver is running.
Option: Aptitude::Suggests-Important
Default: false
Description: This is an obsolete option; use Aptitude::Keep-Suggests instead. Setting this option to true has the same effect as setting Aptitude::Keep-Suggests to true.
Option: Aptitude::Suppress-Read-Only-Warning
Default: false
Description: If this option is false, aptitude will display a warning the first time that you attempt to modify package states while aptitude is in read-only mode.
Option: Aptitude::Theme
Default:
Description: The theme that aptitude should use; see the section called “Themes” for more information.
Option: Aptitude::Track-Dselect-State
Default: true
Description: If this option is set to true, aptitude will attempt to detect when a change to a package's state has been made using dselect or dpkg: for instance, if you remove a package using dpkg, aptitude will not try to reinstall it. Note that this may be somewhat buggy.
Option: Aptitude::UI::Advance-On-Action
Default: false
Description: If this option is set to true, changing a package's state (for instance, marking it for installation) will cause aptitude to advance the highlight to the next package in the current group.
Option: Aptitude::UI::Auto-Show-Reasons
Default: true
Description: If this option is set to true, selecting a package which is broken or which appears to be causing other packages to be broken will cause the information area to automatically display some reasons why the breakage might be occuring.
Option: Aptitude::UI::Default-Grouping
Default: filter(missing),status,section(subdirs,passthrough),section(topdir)
Description: Sets the default grouping policy used for package lists. See the section called “Customizing the package hierarchy” for additional information on grouping policies.
Option: Aptitude::UI::Default-Package-View
Default:
Description: This option is a group whose members define the default layout of aptitude's display. See the section called “Customizing the display layout” for more information.
Option: Aptitude::UI::Default-Preview-Grouping
Default: action
Description: Sets the default grouping policy used for preview screens. See the section called “Customizing the package hierarchy” for additional information on grouping policies.
Option: Aptitude::UI::Default-Sorting
Default: name
Description: The default sorting policy of package views. See the section called “Customizing how packages are sorted” for more information.
Option: Aptitude::UI::Description-Visible-By-Default
Default: true
Description: When a package list is first displayed, the information area (which typically contains the long description of the current package) will be visible if this option is true and hidden if it is false.
Option: Aptitude::UI::Exit-On-Last-Close
Default: true
Description: If this option is true, closing all the active views will quit aptitude; otherwise, aptitude will not exit until you issue the command ActionsQuit (Q). See the section called “Working with multiple views” for more information.
Option: Aptitude::UI::Fill-Text
Default: false
Description: If this option is true, aptitude will format descriptions so that each line is exactly the width of the screen.
Option: Aptitude::UI::HelpBar
Default: true
Description: If this option is true, a line of information about important keystrokes will be displayed at the top of the screen.
Option: Aptitude::UI::Incremental-Search
Default: true
Description: If this option is true, aptitude will perform “incremental” searches: as you type the search pattern, it will search for the next package matching what you have typed so far.
Option: Aptitude::UI::InfoAreaTabs
Default: false
Description: If this option is true, aptitude will display tabs at the top of the information area (the pane at the bottom of the screen) describing the different modes the area can be set to.
Option: Aptitude::UI::Keybindings
Default:
Description: This is a group whose members define the connections between keystrokes and commands in aptitude. For more information, see the section called “Customizing keybindings”.
Option: Aptitude::UI::Menubar-Autohide
Default: false
Description: If this option is set to true, the menu bar will be hidden while it is not in use.
Option: Aptitude::UI::Minibuf-Download-Bar
Default: false
Description: If this option is set to true, aptitude will use a less obtrusive mechanism to display the progress of downloads: a bar at the bottom of the screen will appear which displays the current download status. While the download is active, pressing q will abort it.
Option: Aptitude::UI::Minibuf-Prompts
Default: false
Description: If this option is true, some prompts (such as yes/no and multiple-choice prompts) will be displayed at the bottom of the screen instead of in dialog boxes.
Option: Aptitude::UI::New-Package-Commands
Default: true
Description: If this option is set to false, commands such as PackageInstall (+) will have the same deprecated behavior that they did in antique versions of aptitude.
Option: Aptitude::UI::Package-Display-Format
Default: %c%a%M %p %Z %v %V
Description: This option controls the format string used to display packages in package lists. For more information on format strings, see the section called “Customizing how packages are displayed”.
Option: Aptitude::UI::Package-Header-Format
Default: %N %n #%B %u %o
Description: This option controls the format string used to display the header line of package lists (ie, the line that appears between the package list and the menu bar). For more information on format strings, see the section called “Customizing how packages are displayed”.
Option: Aptitude::UI::Package-Status-Format
Default: %d
Description: This option controls the format string used to display the status line of package lists (ie, the line that appears between the package list and the information area). For more information on format strings, see the section called “Customizing how packages are displayed”.
Option: Aptitude::UI::Pause-After-Download
Default: OnlyIfError
Description: If this option is true, aptitude will display a message after it finishes downloading packages, asking you if you want to continue with the installation. If it is OnlyIfError, a message will only be displayed if a download failed. Otherwise, if the option is set to false, aptitude will immediately proceed to the next screen after completing a download.
Option: Aptitude::Preview-Limit
Default:
Description: The default filter applied to the preview screen; see the section called “Search Patterns” for details about its format.
Option: Aptitude::UI::Prompt-On-Exit
Default: true
Description: If this option is true, aptitude will display a confirmation prompt before shutting down.
Option: Aptitude::UI::Styles
Default:
Description: This is a configuration group whose contents define what textual styles aptitude uses to display information. For more information, see the section called “Customizing text colors and styles”.
Option: Aptitude::UI::ViewTabs
Default: true
Description: If this option is set to false, aptitude will not display “tabs” describing the currently active views at the top of the screen.
Option: Aptitude::Warn-Not-Root
Default: true
Description: If this option is true, aptitude will detect when you need root privileges to do something, and ask you whether you want to switch to the root account if you aren't root already. See the section called “Becoming root for more information.
