I am trying to install quickbox on ubuntu 16.04. I recently formatted my old i5 pc and installed ubuntu. Now I am trying to install quickbox on it, however, whenever I copy and paste the necessary code, "sudoers" file gets damaged. I lose sudo privileges.
I read various articles how to solve this issue but I need a stable solution. I don't want to edit files when this happens.
This error happened when I tried to install quickbox. My computer restarted itself for no reason and this problem was begun.
