Ubuntu – Can’t use the desktop on Ubuntu 19.10 after upgrading from 18.04

19.10upgrade

I just upgraded a system to Ubuntu 19.10 from 18.04. I'm not able to boot into the desktop without seeing this notification:

Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please log out and try again.

If I press the Windows key, I can see the desktop and can click on the icons but the notification will always block me from using the apps.

This is the dialog I am getting:

While booting, before login, press CTRL+ALT+F4. This opens a console and once you log in in the console, try the following commands:

sudo apt-get update && apt-get upgrade
sudo dpkg --configure -a

Once the execution is complete, reboot your system.
