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.

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.
