I just installed smartgithg via ppa:eugenesan/ppa. After an upgrade and restart the whole window style got broken and I can't switch to my preferred keyboard layout. May be some other errors occured as well.
The problem is that this ppa has tons of packages that my system alter in a way I don't want them to do. I just want to install smartgithg and get updates via apt.
So the question is: how to add ppa and just install one package and may be some requirements but do not use this ppa for upgrades?
For now I ppa-purged the ppa. The system is now working again. I'm wondering why smartgithg is still installed. Anyways I won't get updates for it..
