DESCRIPTION

       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.

OPTIONS

   Actions
       -h, --help
              Display this manual.

       -V, --version
              Print version information.

       --arch=architecture
              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
              Perform an apt-get 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
       CHROOT 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.

EXAMPLES

       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
