About backports

Backports are recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates) in a stable environment so that they will run without new libraries (whenever it is possible) on a Debian stable distribution

Backports cannot be tested as extensively as Debian stable, and backports are provided on an as-is basis, with risk of incompatibilities with other components in Debian stable. Use with care!

It is therefore recommended to select single backported packages that fit your needs, and not use all available backports.

Add backports to your sources.list

  1. deb http://deb.debian.org/debian buster-backports main

    to your sources.list (or add a new file with the ".list" extension to /etc/apt/sources.list.d/) You can instead use https when the apt-transport-https package is installed.

  2. Run apt-get update

Install a package from backports

All backports are deactivated by default (i.e. the packages are pinned to 100 by using ButAutomaticUpgrades: yes in the Release files. If you want to install something from backports run:

apt-get -t buster-backports install "package"

of course you can use aptitude as well:

aptitude -t buster-backports install "package"

sloppy distributions

To guarantee a clean upgrade path from a previously stable distribution to the next stable it is not allowed to upload packages from the current testing to that backport distribution. To allow some newer packages for those systems we create so called sloppy distributions.

You can use it exactly as the current backports distribution, just add another line to your sources.list and install new packages via apt-get -t stretch-backports install
