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
