Public bug reported: I am running two laptops with 21.10 and have upgraded both to 22.04 using the following commands:
sudo apt update; sudo apt upgrade sudo update-manager -d THe update manager wizard starts fine and gets about half way through installing new packages. At this point the screen went blank with just a cursor, followed by my Dell system logo (i.e. looking as if it was rebooting). However the system had frozen at this point and required a power cycle to recover. I then used the grub menu to access the restore session and used the dpkg repair option to complete the package installations. When done I rebooted the laptops and the upgrade appears to have completed OK. This will need to be investigated and solved for mainstream release as most users will not wish to manually restore the upgrade in this way.
