Ubuntu noob here,
Was messing around with permissions and external disk mounting options and I think I made a mistake with the permissions. Now I can't install updates and the gnome-desktop won't start. I've tried rebooting to no avail.
I couldn't figure out how to make this display properly here so apologies, let me know if there's a better way.
