Earlier today, I started my Ubuntu VM and a dialogue box asked me if I wanted to update to the latest Ubuntu upgrade package. I clicked OK, but the installation hanged at Firefox Snap. Another dialogue box prompted me to close all my Firefox windows before continuing with the install, but it wouldn't let me click Next even though I had no Firefox window opened. The Ubuntu upgrade was the first thing I did booting up.
My issue looked like this one, so I killed the install as well, and unfortunately, his fix didn't work for me. I still could reboot Ubuntu, and I then launched the Package Manager and attempted to fix my broken package install. I thought I succeeded at first, but upon rebooting Ubuntu again, I get this screen, and then nothing. Boot-up screen
I'm a complete newbie when it comes to Linux/Ubuntu.
Does anyone have any idea how to fix my problem?
