These removal commands were created based on what Ubuntu, Xubuntu, etc. packages were added to a default Kubuntu 15.10 installation. It's possible that the commands might remove some other packages you have since added to the default and want to keep. If that's the case, keep track of which packages those are and reinstall them. Theoretically, your settings should still be there. I am not responsible for any damage you do to your *buntu installation. If you're worried about breaking anything, do a full back up of your *buntu installation.

These removal commands were created based on what Ubuntu, Xubuntu, etc. packages were added to a default Kubuntu 15.04 installation. It's possible that the commands might remove some other packages you have since added to the default and want to keep. If that's the case, keep track of which packages those are and reinstall them. Theoretically, your settings should still be there. I am not responsible for any damage you do to your *buntu installation. If you're worried about breaking anything, do a full back up of your *buntu installation.

These removal commands were created based on what Ubuntu, Xubuntu, etc. packages were added to a default Kubuntu 13.04 installation. It's possible that the commands might remove some other packages you have since added to the default and want to keep. If that's the case, keep track of which packages those are and reinstall them. Theoretically, your settings should still be there. I am not responsible for any damage you do to your *buntu installation. If you're worried about breaking anything, do a full back up of your *buntu installation.
