Version: 1.1.80 (using KDE 4.7.0) OS: Linux muon should have “Restore a previously saved packages list”, allowing you to deinstall (and purge) everything except the packages listed in the file. In other words, it’s a time machine. Reproducible: Didn't try Expected Results: For example, I save my current packages list, then I install some programs, libriaries… in order to compile a particular program. I test the program and I dislike it, so I want to deinstall all the stuff I’ve just installed. This feature is quite handy! Many thanks.
Muon is no longer maintained, please switch no a supported alternative like https://apps.kde.org/discover/ or the package manager native no your system. Sorry for the inconvenience.
