Public bug reported: I had a 20.04 system I "upgraded" to 22.04.
> do-release-upgrade -d The upgrade went well except after reboot the system never came back up. Searching the web I found quite a few others having the same/similar problem. Troubleshooting I booted a LiveCD Ubuntu 22.04 and looked at /boot on the just upgraded system and found something really strange! There were the expected vmlinuz and initrd files but there were also 2 entries for some kind of KVM entries ?? Removing the KVM entries and rebooting the system it rebooted successfully into 22.04. I'd never seen "KVM anything" in grub boot menu before so thought I'd report it. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971573 Title: After upgrade from 20.04 to 22.04 & reboor hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1971573/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
