I turned my computer on this evening to find that my menu is gone. When I open up Gnome tweaks/Extensions I see a little ! in a black box next to the Gno-Menu and the Taskbar. I tried installing ARC menu and cannot get it to work either. The Applications menu does work though. I assume that when I updated some packages (with Add/Remove Software) I broke something. How do I figure out what?
Thanks in advance
