NAME

       sbuild-update - update, upgrade, and clean an sbuild chroot with apt-get

SYNOPSIS

       sbuild-update  [-h|--help]  [-V|--version]  [--arch=architecture] [-u|--update] [-g|--upgrade] [-d|--dist-upgrade] [-c|--clean] [-a|--auto-
       clean] [-r|--autoremove] CHROOT1 [CHROOT2 [CHROOTn...]]
       sbuild-update -k|--keygen
       (DEPRECATED) sbuild-upgrade [-h|--help] [-V|--version] CHROOT1 [CHROOT2 [CHROOTn...]]
       (DEPRECATED) sbuild-distupgrade [-h|--help] [-V|--version] CHROOT1 [CHROOT2 [CHROOTn...]]
       (DEPRECATED) sbuild-clean [-h|--help] [-V|--version] [-c|--clean] [-a|--autoclean] [-r|--autoremove] CHROOT1 [CHROOT2 [CHROOTn...]]

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  sys-
	      tems  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',  'unsta-
	      ble' 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
