## Debian testing or unstable Debian unstable and testing are usually fairly up to date, so this should be enough: sudo apt install git-annex ## Debian 8.0 "jessie" sudo apt install git-annex There is also a backport for jessie, even though it is [often out of date](https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=760787). Follow the instructions to [enable backports](http://backports.debian.org/Instructions/). sudo apt -t jessie-backports install git-annex ## Debian 7.0 "wheezy": sudo apt-get install git-annex Note: This version does not include support for the [[assistant]]. A backport is available with the assistant and other new features. Follow the instructions to [enable backports](http://backports.debian.org/Instructions/). sudo apt-get -t wheezy-backports install git-annex ## Debian 6.0 "squeeze" Follow the instructions to [enable backports](http://backports.debian.org/Instructions/). sudo apt-get -t squeeze-backports install git-annex ## Standalone backports for all releases If the version shipped with Debian is too old, the [NeuroDebian team](http://neuro.debian.net/) provides a [standalone build package](http://neuro.debian.net/pkgs/git-annex-standalone.html) that is regularly updated and that should work across all releases of Debian.
