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.

The sbuild chroot backend of the chroot to update. The autopkgtest backend is not supported by this method because autopkgtest backends are always ephemeral and changes never persist. To update a chroot for schroot and sudo, sbuild-update must be executed with superuser privileges (for example by using sudo). Creating a chroot for the unshare backend can be done by a normal user (without sudo) but it requires Linux user namespaces to be enabled (via "sysctl -w kernel.unprivileged_userns_clone=1"). Defaults to 'schroot'.
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.

To update the unstable chroot:

% 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:

% sbuild-update -udcar unstable
