Software Center doesn't prompt for password
I try to install apps on software center and nothing happens it does'nt ask me to enter my password or anything when i click install it so annoying... It's for all apps.....
Sadly I cannot answer your question, it's very likely that you are still able to install apps via the terminal.
I would recommend trying Synaptic Package Manager
Good luck with the bug! Synaptic Package Manager isn't as pretty, but it's just as good
