sbuild-update runs apt-get inside the specified chroot performing update, upgrade, dist-upgrade, clean, autoclean, and/or autoremove depending on the options specified on the command line.

sbuild-upgrade, sbuild-distupgrade, and sbuild-clean, are deprecated. They now simply run sbuild-update with the appropriate options (--upgrade or --dist-upgrade for sbuild-upgrade or sbuild-distupgrade respectively) along with whatever arguments were passed in the scripts.



-h, --help
Display this manual.
-V, --version
Print version information.
Update chroot for the architecture specified.
-u, --update
Perform an apt-get update.
-g, --upgrade
Perform an apt-get upgrade.
-d, --dist-upgrade
Perform an apt-get dist-upgrade.
-c, --clean
Perform an apt-get clean.
-a, --autoclean
Perform an apt-get autoclean.
-r, --autoremove

-k, --keygen
Generate a GPG public/private key pair for self-signing local apt archives, used for installation of dependency packages. Note that this requires a significant amount of entropy (randomness) and may hang on systems with poor entropy sources, such as headless systems without direct user input. In this situation, it is advisable to create the key on a trusted local system, and copy the files to the build system by hand from /var/lib/sbuild/apt-keys/.

Chroot selection

The chroot to use. Note that 'o', 's', 't', 'u' and 'e' may be used as abbreviations for 'oldstable', 'stable', 'testing', 'unstable' and 'experimental', respectively.

% sbuild-update --update unstable

To upgrade the unstable chroot:

% sbuild-update --upgrade unstable

To clean the unstable chroot:

% sbuild-update --clean unstable

To perform an update, dist-upgrade, clean, autoclean, and autoremove for the unstable chroot:
