I made the mistake of installing Katoolin package https://github.com/LionSec/katoolin. The problem is it botched up my Ubuntu, many packages don't work anymore. System update doesn't work anymore.

The question: is there a way to somehow uninstall this from my Ubuntu without re-installing the OS??

PS: Piece of advice to people who want to study computer security: stay away from this Katoolin tool! Think at least ten times before installing it.

  • If, as you've said, "many packages don't work anymore", then uninstalling will not solve the problems. You might need to backup and then do a clean install. Dec 12, 2015 at 16:18
  • Start with steps in my answer. In point (4), add the output of sudo apt-get install -f here: paste.ubuntu.com and give me the link.

    Thank you! That seems to have solved some problems with removing packages. Some apps still don't work but this should be solved by uninstalling/installing them individually. I'm pretty sure some other people might find this thread useful. Cheers.
