I tried to install a now theme for my Debian 8 Mate. I installed
gtk2-engines-murrine:amd64.deb. as there was missing dependances, I deleted but, I deleted too many packages and now I don't have any theme. I tried to install what I deleted but nothing can revert (gtk2-engines is already installed,).
This is the result of
