Add backports to your sources.list

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.

  1. touch /etc/apt/sources.list.d/backports.list
  2. nano /etc/apt/sources.list.d/backports.list
  3. Add the following line and then save it:
    deb http://deb.debian.org/debian buster-backports main
  4. apt-get update
  5. apt-get -t buster-backports install "package"
