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::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-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 "no".

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::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::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-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')

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.
