After upgrade from 20.04 to 22.04 & reboor hangs

[brian mullan]

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.

I wish I had the log files etc but I was trying to get my system back up.

The explanation I gave is pretty clear
the top 2 entries in the grub boot menu had an odd name including "kvm" in it.
Since those 2 weren't there before I have to assume the Ubuntu "upgrade" process

> do-release-upgrade -d

I deleted those from /boot

updated grub

rebooted

System booted up normally.

This "was" a 20.04 upgraded by

> do-release-upgrade -d

Upgrade succeeded and told me to reboot.

After POST system just hung on "something"
Which led to the previous info

I had done a search and found others asking about the same 22.04 "upgrade" "hang" on askubuntu etc.
