All command line options may be set using the configuration file, the descriptions
       indicate the configuration option to set. For boolean options you can override the config
       file by using something like -f-,--no-f, -f=no or several other variations.

       --no-install-recommends
           Do not consider recommended packages as a dependency for installing. Configuration
           Item: APT::Install-Recommends.

       --install-suggests
           Consider suggested packages as a dependency for installing. Configuration Item:
           APT::Install-Suggests.

       -d, --download-only
           Download only; package files are only retrieved, not unpacked or installed.
           Configuration Item: APT::Get::Download-Only.

       -f, --fix-broken
           Fix; attempt to correct a system with broken dependencies in place. This option, when
           used with install/remove, can omit any packages to permit APT to deduce a likely
           solution. If packages are specified, these have to completely correct the problem. The
           option is sometimes necessary when running APT for the first time; APT itself does not
           allow broken package dependencies to exist on a system. It is possible that a system's
           dependency structure can be so corrupt as to require manual intervention (which
           usually means using dpkg --remove to eliminate some of the offending packages). Use of
           this option together with -m may produce an error in some situations. Configuration
           Item: APT::Get::Fix-Broken.

       -m, --ignore-missing, --fix-missing
           Ignore missing packages; if packages cannot be retrieved or fail the integrity check
           after retrieval (corrupted package files), hold back those packages and handle the
           result. Use of this option together with -f may produce an error in some situations.
           If a package is selected for installation (particularly if it is mentioned on the
           command line) and it could not be downloaded then it will be silently held back.
           Configuration Item: APT::Get::Fix-Missing.

       --no-download
           Disables downloading of packages. This is best used with --ignore-missing to force APT
           to use only the .debs it has already downloaded. Configuration Item:
           APT::Get::Download.

       -q, --quiet
           Quiet; produces output suitable for logging, omitting progress indicators. More q's
           will produce more quiet up to a maximum of 2. You can also use -q=# to set the quiet
           level, overriding the configuration file. Note that quiet level 2 implies -y; you
           should never use -qq without a no-action modifier such as -d, --print-uris or -s as
           APT may decide to do something you did not expect. Configuration Item: quiet.

       -s, --simulate, --just-print, --dry-run, --recon, --no-act
           No action; perform a simulation of events that would occur based on the current system
           state but do not actually change the system. Locking will be disabled
           (Debug::NoLocking) so the system state could change while apt-get is running.
           Simulations can also be executed by non-root users which might not have read access to
           all apt configuration distorting the simulation. A notice expressing this warning is
           also shown by default for non-root users (APT::Get::Show-User-Simulation-Note).
           Configuration Item: APT::Get::Simulate.

           Simulated runs print out a series of lines, each representing a dpkg operation:
           configure (Conf), remove (Remv) or unpack (Inst). Square brackets indicate broken
           packages, and empty square brackets indicate breaks that are of no consequence (rare).

       -y, --yes, --assume-yes
           Automatic yes to prompts; assume "yes" as answer to all prompts and run
           non-interactively. If an undesirable situation, such as changing a held package,
           trying to install a unauthenticated package or removing an essential package occurs
           then apt-get will abort. Configuration Item: APT::Get::Assume-Yes.

       --assume-no
           Automatic "no" to all prompts. Configuration Item: APT::Get::Assume-No.

       --no-show-upgraded
           Do not show a list of all packages that are to be upgraded. Configuration Item:
           APT::Get::Show-Upgraded.

       -V, --verbose-versions
           Show full versions for upgraded and installed packages. Configuration Item:
           APT::Get::Show-Versions.

       -a, --host-architecture
           This option controls the architecture packages are built for by apt-get source
           --compile and how cross-builddependencies are satisfied. By default is it not set
           which means that the host architecture is the same as the build architecture (which is
           defined by APT::Architecture). Configuration Item: APT::Get::Host-Architecture.

       -P, --build-profiles
           This option controls the activated build profiles for which a source package is built
           by apt-get source --compile and how build dependencies are satisfied. By default no
           build profile is active. More than one build profile can be activated at a time by
           concatenating them with a comma. Configuration Item: APT::Build-Profiles.

       -b, --compile, --build
           Compile source packages after downloading them. Configuration Item: APT::Get::Compile.

       --ignore-hold
           Ignore package holds; this causes apt-get to ignore a hold placed on a package. This
           may be useful in conjunction with dist-upgrade to override a large number of undesired
           holds. Configuration Item: APT::Ignore-Hold.

       --with-new-pkgs
           Allow installing new packages when used in conjunction with upgrade. This is useful if
           the update of a installed package requires new dependencies to be installed. Instead
           of holding the package back upgrade will upgrade the package and install the new
           dependencies. Note that upgrade with this option will never remove packages, only
           allow adding new ones. Configuration Item: APT::Get::Upgrade-Allow-New.

       --no-upgrade
           Do not upgrade packages; when used in conjunction with install, no-upgrade will
           prevent packages on the command line from being upgraded if they are already
           installed. Configuration Item: APT::Get::Upgrade.

       --only-upgrade
           Do not install new packages; when used in conjunction with install, only-upgrade will
           install upgrades for already installed packages only and ignore requests to install
           new packages. Configuration Item: APT::Get::Only-Upgrade.

       --allow-downgrades
           This is a dangerous option that will cause apt to continue without prompting if it is
           doing downgrades. It should not be used except in very special situations. Using it
           can potentially destroy your system! Configuration Item: APT::Get::allow-downgrades.
           Introduced in APT 1.1.

       --allow-remove-essential
           Force yes; this is a dangerous option that will cause apt to continue without
           prompting if it is removing essentials. It should not be used except in very special
           situations. Using it can potentially destroy your system! Configuration Item:
           APT::Get::allow-remove-essential. Introduced in APT 1.1.

       --allow-change-held-packages
           Force yes; this is a dangerous option that will cause apt to continue without
           prompting if it is changing held packages. It should not be used except in very
           special situations. Using it can potentially destroy your system! Configuration Item:
           APT::Get::allow-change-held-packages. Introduced in APT 1.1.

       --force-yes
           Force yes; this is a dangerous option that will cause apt to continue without
           prompting if it is doing something potentially harmful. It should not be used except
           in very special situations. Using force-yes can potentially destroy your system!
           Configuration Item: APT::Get::force-yes. This is deprecated and replaced by
           --allow-unauthenticated , --allow-downgrades , --allow-remove-essential ,
           --allow-change-held-packages in 1.1.

       --print-uris
           Instead of fetching the files to install their URIs are printed. Each URI will have
           the path, the destination file name, the size and the expected MD5 hash. Note that the
           file name to write to will not always match the file name on the remote site! This
           also works with the source and update commands. When used with the update command the
           MD5 and size are not included, and it is up to the user to decompress any compressed
           files. Configuration Item: APT::Get::Print-URIs.

       --purge
           Use purge instead of remove for anything that would be removed. An asterisk ("*") will
           be displayed next to packages which are scheduled to be purged.  remove --purge is
           equivalent to the purge command. Configuration Item: APT::Get::Purge.

       --reinstall
           Re-install packages that are already installed and at the newest version.
           Configuration Item: APT::Get::ReInstall.

       --list-cleanup
           This option is on by default; use --no-list-cleanup to turn it off. When it is on,
           apt-get will automatically manage the contents of /var/lib/apt/lists to ensure that
           obsolete files are erased. The only reason to turn it off is if you frequently change
           your sources list. Configuration Item: APT::Get::List-Cleanup.

       -t, --target-release, --default-release
           This option controls the default input to the policy engine; it creates a default pin
           at priority 990 using the specified release string. This overrides the general
           settings in /etc/apt/preferences. Specifically pinned packages are not affected by the
           value of this option. In short, this option lets you have simple control over which
           distribution packages will be retrieved from. Some common examples might be -t '2.1*',
           -t unstable or -t sid. Configuration Item: APT::Default-Release; see also the
           apt_preferences(5) manual page.

       --trivial-only
           Only perform operations that are 'trivial'. Logically this can be considered related
           to --assume-yes; where --assume-yes will answer yes to any prompt, --trivial-only will
           answer no. Configuration Item: APT::Get::Trivial-Only.

       --no-remove
           If any packages are to be removed apt-get immediately aborts without prompting.
           Configuration Item: APT::Get::Remove.

       --auto-remove, --autoremove
           If the command is either install or remove, then this option acts like running the
           autoremove command, removing unused dependency packages. Configuration Item:
           APT::Get::AutomaticRemove.

       --only-source
           Only has meaning for the source and build-dep commands. Indicates that the given
           source names are not to be mapped through the binary table. This means that if this
           option is specified, these commands will only accept source package names as
           arguments, rather than accepting binary package names and looking up the corresponding
           source package. Configuration Item: APT::Get::Only-Source.

       --diff-only, --dsc-only, --tar-only
           Download only the diff, dsc, or tar file of a source archive. Configuration Item:
           APT::Get::Diff-Only, APT::Get::Dsc-Only, and APT::Get::Tar-Only.

       --arch-only
           Only process architecture-dependent build-dependencies. Configuration Item:
           APT::Get::Arch-Only.

       --indep-only
           Only process architecture-independent build-dependencies. Configuration Item:
           APT::Get::Indep-Only.

       --allow-unauthenticated
           Ignore if packages can't be authenticated and don't prompt about it. This can be
           useful while working with local repositories, but is a huge security risk if data
           authenticity isn't ensured in another way by the user itself. The usage of the Trusted
           option for sources.list(5) entries should usually be preferred over this global
           override. Configuration Item: APT::Get::AllowUnauthenticated.

       --no-allow-insecure-repositories
           Forbid the update command to acquire unverifiable data from configured sources. APT
           will fail at the update command for repositories without valid cryptographically
           signatures. See also apt-secure(8) for details on the concept and the implications.
           Configuration Item: Acquire::AllowInsecureRepositories.

       --allow-releaseinfo-change
           Allow the update command to continue downloading data from a repository which changed
           its information of the release contained in the repository indicating e.g a new major
           release. APT will fail at the update command for such repositories until the change is
           confirmed to ensure the user is prepared for the change. See also apt-secure(8) for
           details on the concept and configuration.

           Specialist options (--allow-releaseinfo-change-field) exist to allow changes only for
           certain fields like origin, label, codename, suite, version and defaultpin. See also
           apt_preferences(5). Configuration Item: Acquire::AllowReleaseInfoChange.

       --show-progress
           Show user friendly progress information in the terminal window when packages are
           installed, upgraded or removed. For a machine parsable version of this data see
           README.progress-reporting in the apt doc directory. Configuration Items:
           Dpkg::Progress and Dpkg::Progress-Fancy.

       --with-source filename
           Adds the given file as a source for metadata. Can be repeated to add multiple files.
           See --with-source description in apt-cache(8) for further details.

       -h, --help
           Show a short usage summary.

       -v, --version
           Show the program version.

       -c, --config-file
           Configuration File; Specify a configuration file to use. The program will read the
           default configuration file and then this configuration file. If configuration settings
           need to be set before the default configuration files are parsed specify a file with
           the APT_CONFIG environment variable. See apt.conf(5) for syntax information.

       -o, --option
           Set a Configuration Option; This will set an arbitrary configuration option. The
           syntax is -o Foo::Bar=bar.  -o and --option can be used multiple times to set
           different options.
