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
