I have a crash dummy system that has been running flawlessly on 20.04 LTS for several years. I clicked on the upgrade to 22.04.1 LTS button and it downloaded and installed what looks like most of the packages. I was presented with an info popup saying that Firefox is only available through snap. Clicking the "next" button does nothing. I have a dual monitor system and on the other monitor it displays a "whoops, something went wrong" pad. Clicking the logout button on that pad did nothing.
Rebooting gives me the same "something went wrong" pad and of course I can't log in. Needless to say I am not real impressed with this poorly tested upgrade.
I can ssh in to the system and it shows the old kernel but gives a 22.04.1 LTS welcome message. Gnome seems to be running but I have that error pad displayed instead of a login.

This upgrade should have gone smoothly like all of the previous LTS upgrades I have done but it obviously didn't. I could really use some help from someone who really knows what they are talking about since there seems to be something seriously broken in the upgrade script. At this point I can't get the gnome GUI to give me a login screen for 20.04 LTS and I can't go forward with the 22.04.1 LTS upgrade so the system is now totally broken.
I can ssh in from another system. The screen on the target system gives the message "A problem has occurred and the system can't recover. Contact a systems administrator.
How do I recover from this? Thanks in advance.
