Kernel Panic after upgrading from 22.10 to 23.04

in flag

After using the common way of upgrading via GNOME desktop I got an error msg, that the kernel and/or header files could not get installed.

When restarting the machine It tries to start with 23.04 which fails and outputs a kernel panic.

/dev/root: Can't open blockdev 
Kernel panic - not syncing: VFS: Unable to mountroot fs on unknown-block(0,0) 
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 6.2.0-20-generic #20-Ubuntu

When I choose to boot with the old kernel (5.19) everything works.

Any idea how I can restart the whole upgrade process or do a full downgrade back to 22.10 or 22.04LTS? Thanks in advance :)

Some infos on the machine:

  • Fujitsu Lifebook U7511
  • Kernel: x86_64 Linux 5.19.0-40-generic
  • CPU: 11th Gen Intel Core i5-1135G7 @ 8x 4,2GHz
  • GPU: Iris Xe Graphics

Had a similar problem. The dkms module evid-dkms for displaylink blocked the kernel module build during installation. After uninstalling

sudo dkms remove evdi/1.11.0 --all

and upgrading agian

sudo apt upgrade

the kernel module we're built and the error is gone.

Thanks Robert, this has resolved my issue too, although I had to modify it. After first running `sudo apt upgrade` to see why it was failing, it mentioned evdi version 5.2.14, so I was surprised to see 1.11.0 in your command. Anyway, I ran `sudo dkms remove evdi/5.2.14 --all`, and after doing that the upgrade worked fine. (I had also previously tried removing the other installed version, 1.9.0 that I found in /var/lib/dkms/evdi, as the make.log file for this module was showing errors, but it didn't resolve the issue).

This would be better as an answer not a comment to an answer. You did something different therefore a different answer.

Reinstalling displaylink version 5.7.0.61 solved my problem.

Synaptics Displaylink Driver Download

I performed $ sudo displaylink-installer uninstall, restarted and then reinstalled with

$ sudo chmod +x displaylink-driver-5.7.0-61.129.run
$ sudo ./displaylink-driver-5.7.0-61.129.run

I did a $ sudo apt install && sudo apt upgrade afterwards and the error was fixed.

Found the solution here: https://askubuntu.com/a/1464554/1087722

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
