Can't boot in new kernel. Upgrade suddently went dark screen with no warning in the middle of upgrade. Manually rebooted possibly in the middle of it doing something (it told me nothing about going dark or how long or anything so I have no way to know).

Trying to upgrade to 23.04 from 22.10.

Now system under older kernel says 23.04 but everything is weird and slow. Unclear what to do next. Will try to see if can rerun the kernel update somehow.

You have an unsupported DKMS module installed that broke the kernel upgrade. Remove it and retry the upgrade:

$ dkms remove 8812au/4.2.3 --all
$ apt update
$ apt upgrade
