NAME

       cdist-type__apt_backports - Install backports

DESCRIPTION

       This singleton type installs backports for the current OS release.  It aborts if backports
       are not supported for the specified OS or no  version  codename  could  be  fetched  (like
       Debian unstable).

       The package index will be automatically updated if required.

       It supports backports from following OSes:

       • Debian

       • Devuan

       • Ubuntu

REQUIRED PARAMETERS

       None.

OPTIONAL PARAMETERS

       state  Represents  the  state  of the backports repository. present or absent, defaults to
              present.

              Will be directly passed to cdist-type__apt_source(7).

       mirror The mirror to fetch the backports from. Will defaults to the generic mirror of  the
              current OS.

              Will be directly passed to cdist-type__apt_source(7).

BOOLEAN PARAMETERS

       None.

       None.

EXAMPLES

          # setup the backports
          __apt_backports
          __apt_backports --state absent
          __apt_backports --state present --mirror "http://ftp.de.debian.org/debian/"

          # install a backports package
          # currently for the buster release backports
          require="__apt_backports" __package_apt wireguard \
               --target-release buster-backports

ABORTS

       Aborts if the detected os is not Debian.

       Aborts  if  no  distribuition  codename could be detected. This is common for the unstable
       distribution, but there is no backports repository for it already.

CAVEATS

       For Ubuntu, it setup all componenents for  the  backports  repository:  main,  restricted,
       universe and multiverse. The user may not want to install proprietary packages, which will
       only be installed if the user explicitly uses the backports target-release. The  user  may
       change  this  behavior to install backports packages without the need of explicitly select
       it.
