Removing Katoolin from Ubuntu 14.04

Question

I made the mistake of installing this (piece of cr*p of) 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 pest 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.
