PPAs (Personal Package Archives) are a popular way to install pre-built packages that for some reason are not (yet) available in Ubuntu’s standard package repositories. Some common examples that come to my mind:
Eventually, if you’re lucky1 you might not need the packages from the PPA anymore, so this brings us to the question of today’s article - how can you quickly remove everything you installed from a PPA? If you installed only a single package that’s not a big deal, but you might have installed dozens of packages from one PPA. A good example would be oibaf/graphics-drivers. Once you no longer need the newest drivers (e.g. after a distro upgrade) you can remove all of them like this:
$ sudo apt install ppa-purge $ sudo ppa-purge ppa:oibaf/graphics-drivers
This will remove all packages installed from the PPA. Depending on whether the packages exist in other enabled repos or not that might result in downgrade or complete removal of those packages. In the specific example I’ve given we’d just downgrade all video driver packages to their versions available in Ubuntu’s own repos.
That’s all I have for you today. Keep hacking!
Or unlucky - imagine some snapshot versions crashing constantly. ↩
