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.

   Chroot selection
       --chroot-mode=schroot|sudo|unshare
              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'.

       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
