Howto mix releases

If you want to install some packages from testing without upgrading your whole stable system to testing you can tell apt how to deal with different releases:

  1. add testing and/or unstable repos to your sources.list
  2. edit apt.conf
  3. edit preferences
  4. apt-get install […]

Recommended reading:


APT::Default-Release "stable";


Package: *
Pin: release a=stable
Pin-Priority: 900

Package: *
Pin: release a=testing
Pin-Priority: 90

What the pin priorities mean:


  • apt-cache policy foo
  • apt-show-versions

Howto invoke apt-get

  • apt-get install foo/testing
  • apt-get install foo=1.0-1
  • apt-get install –target-release testing foo
