cupt.conf - configuration file for Cupt


$APT_CONFIG, /etc/apt/apt.conf, /etc/apt/apt.conf.d/*, $CUPT_PRE_CONFIG, /etc/cupt/pre.conf, /etc/cupt/cupt.conf, /etc/cupt/cupt.conf.d/*


Cupt uses the same configuration syntax as apt.conf(5), which see.


Firstly, Cupt uses following APT configuration variables: acquire::*::dl-limit, acquire::*::timeout, acquire::*::proxy, acquire::http::allowredirect, acquire::retries, apt::cache::allversions, apt::cache::important, apt::cache::namesonly, apt::cache::recursedepends, apt::default-release, apt::install-recommends, apt::install-suggests, apt::neverautoremove, apt::get::assume-yes, apt::get::allowunauthenticated, apt::get::automaticremove, apt::get::list-cleanup, apt::get::purge, apt::update::pre-invoke, apt::update::post-invoke, apt::update::post-invoke-success, dir, dir::bin::dpkg, dir::cache, dir::cache::archives, dir::etc, dir::etc::sourcelist, dir::etc::sourceparts, dir::etc::parts, dir::etc::main, dir::etc::preferences, dir::ignore-files-silently, dir::state, dir::state::extendedstates, dir::state::status, dir::etc::trusted, dir::etc::trustedparts dpkg::options, dpkg::pre-invoke, dpkg::post-invoke, dpkg::pre-install-pkgs, quiet See apt.conf(5) for their meanings. Secondly, Cupt introduces cupt-specific configuration variables. variable types boolean false may be specified as "0" or "false" or "no", everything else interpretes as true if undefined, interpretes as false integer signed 32-bit integer on 32-bit systems, signed 64-bit integer on 64-bit systems if undefined, interpretes as 0 string interpreted as is if undefined, interpretes as empty string list list of strings if undefined, intepretes as empty list variables cupt::cache::limit-releases::by-*::type string, determines the type of limiting repository releases to use All repository indexes which are disallowed by this option are not added to the package cache, in other words, they are completely hidden. '*' can be 'archive' or 'codename' Possible values: none No limiting will be done for this category. The default. include Only values of the 'cupt::cache::limit-releases::by-*' option will be allowed. exclude Only values which are not present in the value of the 'cupt::cache::limit-releases::by-*' option will be allowed. Example: If you set 'cupt::cache::limit-releases::by-archive::type' to 'include' and 'cupt::cache::limit-releases::by-archive' to '{ "stable", "testing" };', only repositories with archive names 'stable' and 'testing' will be added to the cache. cupt::cache::limit-releases::by-* list of allowed/disallowed release attributes, see above cupt::cache::pin::addendums::but-automatic-upgrades integer, specifies priority change for versions that come only from sources which have both 'not automatic' and 'but automatic upgrades' flags. Defaults to 4200. cupt::cache::pin::addendums::downgrade integer, specifies priority change for versions that are smaller than currently installed. Defaults to -10000. cupt::cache::pin::addendums::hold integer, specifies priority increase for versions that are put on hold. Defaults to 1000000. Set this option to 0 if you do not want to obey holds. You may want to increase this option in (very unlikely to happen) situations: when you have thousands of manually installed packages and very large query; when you have a manually crafted pin priorities system with very large pin values. cupt::cache::pin::addendums::not-automatic integer, specifies priority increase for versions that come only from 'not automatic' sources. Defaults to -4000. If you change the value of this option, you might want to change the value of the option "cupt::cache::pin::addendums::but-automatic-upgrades" accordingly. cupt::cache::release-file-expiration::ignore boolean, if set to true, Cupt will ignore the fact that a Release file is expired and use it anyway. False by default. Warning! Setting this option to true will make the system vulnerable to a replay attack on package manager indexes. cupt::console::allow-untrusted boolean, don't treat using untrusted packages as dangerous action cupt::console::assume-yes boolean, see cupt(1) --assume-yes cupt::console::actions-preview::package-indicators::manually-installed boolean, whether to print "{m}" prefix for manually installed packages in non-color mode. Enabled by default. cupt::console::actions-preview::package-indicators::automatically-installed boolean, whether to print "{a}" prefix for automatically installed packages in non- color mode. Disabled by default. cupt::console::actions-preview::show-not-preferred string, determines whether packages which will have a not preferred version after the proposed changes are done should be shown in the actions preview. Defaults to 'for-upgrades'. Possible values: no Do not show. for-upgrades Show for upgrade subcommands (namely, for "full-upgrade", "safe-upgrade" and the second part of "dist-upgrade"). yes Show always. cupt::console::actions-preview::show-archives boolean, if true, release archive(s) will be shown for each package in the actions preview. False by default. cupt::console::actions-preview::show-codenames boolean, if true, release codename(s) will be shown for each package in the actions preview. False by default. cupt::console::actions-preview::show-components boolean, if true, release component(s) will be shown for each package in the actions preview. False by default. cupt::console::actions-preview::show-details boolean, if true, details of planned actions will be shown in the actions preview. True by default. cupt::console::actions-preview::show-empty-versions boolean, if true, empty versions (i.e. removed or not installed packages) will be shown as '<empty>' instead of being omitted cupt::console::actions-preview::show-size-changes boolean, if true, a change in the disk space usage will be shown for each package in the actions preview. False by default. cupt::console::actions-preview::show-reasons boolean, see cupt(1) --show-reasons cupt::console::actions-preview::show-summary string, tristate ("yes", "no" or "auto"), controls whether summary of planned actions will be shown in the actions preview or not. Defaults to "yes". Currently, "auto" means that summary will be shown when there are >= 100 change entries in total. cupt::console::actions-preview::show-versions boolean, if true, a version will be shown for each package in the actions preview. False by default. cupt::console::actions-preview::show-vendors boolean, if true, a version will be shown for each package in the actions preview. False by default. cupt::console::show-progress-messages boolean, if true, package management actions will print stage messages ("Building a cache", "Resolving possible unmet dependencies" etc.). True by default. cupt::console::use-colors string, specifies whether to use colors in the console interface. Defaults to "auto". For now concerns only the action preview. Available values: no Don't use colors. yes Use colors. auto Use colors if the standard output is a terminal and a terminal type seem to allow colors. cupt::console::warnings::removal-of-essential boolean, treat removals of essential packages as dangerous action. True by default. cupt::console::warnings::removal-of-important boolean, treat removals of important packages as dangreous action. True by default. cupt::directory string, base directory for all cupt::directory::* options cupt::directory::configuration string, base directory for Cupt-specific configuration files cupt::directory::configuration::main string, relative file path for the Cupt main configuration file (same format as apt.conf(5)) cupt::directory::configuration::main-parts string, relative directory path for additional Cupt configuration files (same format as apt.conf(5)) cupt::directory::configuration::pre string, relative file path for the Cupt preconfiguration file which is read before paths of any other configuration files are calculated. This is the only place where one can effectively override default values of dir::etc and cupt::directory::configuration options and/or their suboptions. The environment variable CUPT_PRE_CONFIG overrides this option if defined. cupt::directory::log string, relative file path for the log file cupt::directory::state string, directory which contains Cupt state info cupt::directory::state::lists string, directory for repository indexes cupt::downloader::max-simultaneous-downloads integer, positive, specifies maximum number of simultaneous downloads. Defaults to 2. cupt::downloader::protocols::protocol::priority integer, positive, defines the priority of download protocol protocol, determines an order in which different URIs for the same file will be tried. Defaults to 100. cupt::downloader::protocols::protocol::methods::method::priority positive number, defines the priority of download method method, the method with maximum priority will be used for downloading the URI of protocol protocol. Defaults to 100. cupt::downloader::protocols::protocol::methods list, names of the methods available to download protocol protocol cupt::languages::indexes string, specifies localizations of what languages should be used for repository indexes. Defaults to "environment,en". The value is comma-delimited (no spaces allowed) list of localization specificators. Localization specificator is either: environment A special string which is substituted by the current locale (precisely, by a value of the environment variable LC_MESSAGES). none A special string which indicates no localization. language_code[_country_code] A language code (for example: 'fi', 'fr', 'ru') or a language code with a country code (for example, 'pt_BR', 'zh_CN'). If the localization specificator contains a country code, the additional specificator without a country code will be implicitly used as fallback. Localization specificators should be listed in the preference order. Duplicates are allowed but ignored. Examples: fi,ru,fr Download Finnish, Russian and French translations. For every description, try to use Finnish translation; if it's not available, try to use Russian one; if it's also not available; try to use French one; else use an original one. pt_BR Download Portuguese (Brazil) and Portuguese localizations. Use Portuguese (Brazil) translation; if it's not available, use Portuguese translation; else use an original one. de,environment,fr_FR (Supposing LC_MESSAGES is 'pl_PL.UTF-8') Download and use these translations, in the following order: German, Polish (Poland), Polish, French (France), French. cupt::update::check-release-files boolean, if set, Release files will be checked for the validity (including the expiration check and a signature if present) at the download stage. True by default. cupt::update::compression-types::*::priority integer, defines preference to download compressed files with higher priority first. 100 by default. '*' can be 'gz', 'bz2', 'lzma', 'xz', and 'uncompressed'. Set some option to <100 value to make it low-precedence than default, and >100 to make it high-precedence than default. If some methods have the equal priority (which is the default setting), then files with smaller size with be chosen over the files with bigger size. Example: You have a low-speed CPU but rather high-speed internet connection and want to prefer gzip over lzma and lzma over bzip2. Then you have to set options like: cupt::update::compression-types { gz::priority "200"; lzma::priority "150"; } Also, if you have a local mirror, which may store uncompressed indexes too (an official Debian archive doesn't store them), you may set also cupt::update::compression-types::uncompressed::priority "300"; cupt::update::generate-index-of-index boolean, specifies whether to build "index-of-index" for every Packages and Sources. If set to true, slightly increases the time of postprocessing after downloading new metadata files but speedes up significantly the initialization time for every invocation. True by default. cupt::update::use-index-diffs boolean, specifies whether to try downloading repository index deltas and apply them locally before downloading the full index. True by default. When turned on, this option saves bandwidth but increases CPU and disk usage while updating. On the fast unlimited connections (say, >= 2 Mbit/s, but heavily depends on many other factors) you would likely want to turn off this option. cupt::resolver::keep-recommends boolean, specifies whether should resolver try to keep already installed recommended packages or not. True by default. cupt::resolver::keep-suggests boolean, specifies whether should resolver try to keep already installed suggested packages or not. False by default. cupt::resolver::auto-remove boolean, see cupt(1) --no-auto-remove cupt::resolver::max-leaf-count integer, specifies how many leaves the solution tree will grow before resolver will give up. -1 means infinite. -1 by default. cupt::resolver::max-solution-count integer, positive, see cupt(1) --max-solution-count cupt::resolver::no-autoremove-if-rdepends-exist list of regular expressions; if the package name matches to any of those regular expressions it will be not considered for auto-removal if there are any reverse dependencies installed. Empty by default. Example (simplified real situation): Package: xserver-xorg Depends: xserver-xorg-video-all | xorg-driver-video Package: xserver-xorg-video-nv Provides: xorg-driver-video Package: xserver-xorg-video-radeon Provides: xorg-driver-video You have: xserver-xorg: manually installed xserver-xorg-video-all: not installed xserver-xorg-video-nv: automatically installed xserver-xorg-video-radeon: automatically installed Both xserver-xorg-video-nv and xserver-xorg-video-radeon satisfy the dependency of xserver-xorg, so only one of them is needed in the system. Therefore, by default one of these two will be considered for auto-removal. If you add a regular expression 'xserver-xorg-video.*' to the value of this option, none of packages providing xorg- driver-video will be considered for auto-removal as long as xserver-xorg is installed. cupt::resolver::no-remove boolean, see cupt(1) --no-remove cupt::resolver::synchronize-by-source-versions string, this option controls whether and how the native resolver will attempt to keep all binary packages from the same source package at the same source version This option uses the information from source packages. No synchronization will be performed for the versions which have not a corresponding source version in the repository. Possible values: none Don't attempt to synchronize. This is the default value. soft Don't forbid any modifications to the packages and attempt to synchronize related binary packages when possible upon the modifications of certain binary package. hard Forbid any modifications to the packages when at least one related binary package cannot be synchronized with the modified one. cupt::resolver::track-reasons boolean, specifies whether 'suggestedPackages::reasons' is filled in the Resolver::Offer. False by default. cupt::resolver::type string, see cupt(1) --resolver cupt::resolver::score::<part> The group of integer options which control internal resolver's score calculation. Values are absolute. <part> can be one of: new installing a new package removal removal of an existing package removal-of-essential removal of an existing essential package (a general removal option is applied as well) removal-of-autoinstalled removal of an automatically installed package (a general removal option is applied as well) upgrade installing a higher version of an existing package downgrade installing a lower version of an existing package position-penalty when several actions may be performed to resolve a problem, apply N penalties to N-th action (counting from 0) quality-adjustment the value will be added to each action's score unsatisfied-recommends some 'recommends' dependency is not satisfied (when requested) unsatisfied-suggests some 'suggests' dependency is not satisfied (when requested) failed-synchronization some source version synchronization cannot be performed (when cupt::resolver::synchronize-source-versions is 'soft') version-factor::common defines (in percents), how much version score difference affects the action score version-factor::negative defines (in percents) scaling of negative version scores (applied after version- factor) version-factor::priority-downgrade defines (in percents) scaling of version score if version priority difference is negative. For calculations regarding this factor, if there is no original version, its priority is 0, if there is no supposed version, its priority is the default priority for versions from a default package archive. cupt::worker::archives-space-limit integer, bytes, positive, if set, limits the worker to not download more than specified amount of archives, and use download-install-clean algorithm (download archives, install packages, clean just downloaded archives). Worker will try to split all actions into unrelated changesets so each changeset require only limited download space. Any system changes will be started only if changesets are generated successfully. cupt::worker::defer-triggers string, specifies whether should worker defer dpkg trigger processing to the end of the whole operation or not. When enabled, speeds up large-amount actions, but if the operation will somewhy be interrupted, leaves system in the interim trigger state, which can be fixed by manual run of 'dpkg --triggers-only --pending' command. Defaults to "auto". Available values: no Disable deferring triggers. yes Enable deferring triggers. auto Enable deferring triggers if enough recent version of dpkg (1.16.1, where tiresome trigger-related bug (Debian BTS #526774) is fixed) is installed. cupt::worker::download-only boolean, see cupt(1) --download-only cupt::worker::log boolean, whether to log performed actions or not. True by default. cupt::worker::log::levels::metadata non-negative integer, the log level for the metadata updates. 1 by default. cupt::worker::log::levels::packages non-negative integer, the log level for the package changes (install/upgrade/remove etc.). 2 by default. cupt::worker::log::levels::snapshots non-negative integer, the log level for the snapshot actions. 1 by default. cupt::worker::purge boolean, specifies whether purge packages in addition to removing or not. False by default. cupt::worker::simulate boolean, see cupt(1) --simulate cupt::worker::use-locks boolean, specifies whether Cupt protects simultaneous runs of itself against the misuse of the common resources. True by default. Warning! Setting this option to false will allow several non-simulating Cupt instances to break the system when misused. debug::resolver boolean, if true, resolver will print a lot of debug information to the standard error. False by default. debug::worker boolean, if true, worker will print some debug information to the standard error. False by default. debug::gpgv boolean, if true, cache will print some debug information while verifying signatures to the standard error. False by default. debug::downloader boolean, if true, the downloader manager will print some debug messages. False by default. debug::logger boolean, if true, the logger will print some debug messages. False by default.
