The right click menu on my desktop no longer has an option to launch the terminal.
Brief history: I was messing around with my locale file and ended up breaking unity. There was no desktop, no launcher, no menu bar after booting up. I managed to restore unity by following the top two answers here: unity is not working after upgrade to ubuntu 15.10
But after that my terminal disappeared. It appeared in my dash search but wouldn't open. Ctrl-Alt-T, the option in the right click menu: nothing worked.
So I removed and reinstalled gnome-terminal. But the option from the right click menu has stayed absent.
