DebianReleases > Debian Experimental
The experimental repository
Contents
Introduction
Quoting the Debian FAQ:"project/experimental/: This directory contains packages and tools which are still being developed, and are still in the alpha testing stage. Users shouldn't be using packages from here, because they can be dangerous and harmful even for the most experienced people."
You have been warned
Unlike the Debian Releases unstable and testing, experimental isn't a complete distribution, it can work only as an extension of unstable. So packages in experimental can depend on packages in unstable but packages in unstable cannot depend on packages in experimental. Experimental is a staging/collaboration/experimental area for development, when it is known that a package has problems or may have problems. Some packages/developers don't use experimental, they just put the new versions in unstable. The migration of packages from experimental to unstable is entirely at discretion of the packagers. Even if there are a lot less consistency requirements for packages in experimental, they are autobuilt on the best effort basis by official Debian Package Auto-Building infrastructure.
To configure APT
An /etc/apt/sources.list entry for experimental is:
deb https://deb.debian.org/debian experimental main
To install an experimental package
To install an experimental package, do:
apt update apt -t experimental install packagename
To upgrade an experimental package
If the package has changed in experimental and you want to upgrade it, do:
apt update apt -t experimental install packagename
APT pinning
Optionally, if you want to track a given package from experimental, add the following to /etc/apt/preferences (and see AptPreferences):
Package: dash Pin: release a=experimental Pin-Priority: 800
Listing all packages installed from experimental
To check which experimental packages are currently installed on your system, do:
aptitude search ~S~i~Aexperimental
