Also a good way: Install package deborphan, then run aptitude purge `deborphan --guess-all`. Be carefull, what it wants do deinstall. However, I am using it regularly and it did not deinstall accidently a package, I did not want to be deinstalled. Ok, might be, I was lucky. If it does, I would just reinstall it. I suggest, just to take a look and then decide for yourself. Best regards Hans
