Just a few minutes ago, there were updates waiting so I chose to install them (from the GUI), and much to my surprise, I see that it tries to install oracle and lowlatency kernels. The process failed during config phase and now the following packages are “half-conf”.

iF  linux-image-6.2.0-1005-oracle                  6.2.0-1005.5                               amd64        Signed kernel image oracle
iF  linux-image-6.2.0-1007-lowlatency              6.2.0-1007.7                               amd64        Signed kernel image lowlatency

Considering :

  • I only had generic kernels installed
  • I didn’t install any new packages in months
  • Previous recent updates worked with no problem

Can someone explain what just happened ?

EDIT :

I found here and there, posts and bug reports that are hinting towards an unrequested kernel stack change :

So, 22.04 and 23.04 seem to be affected.

My (wild) guess is, it’s related to ubuntu-drivers-common and only concerns people with an Nvidia GPU, the system being hinted towards a wrong driver from another kernel stack.

  • @user535733 Do you have the proprietary Nvidia driver installed ? I’m suspecting the problem may come from ubuntu-drivers-common that decided to install drivers from kernel stacks that were not installed, which then brought the kernel images, because dependencies – NovHak Jul 02 '23 at 00:38
  • @user535733 Indeed, maybe they are not, but it’s not like they were submitted years apart, it’s in the same time frame (<24h). Moreover, some posts explicitly complain about kernels from another stack being installed, which imho is more than sort of similar. – NovHak Jul 02 '23 at 01:29
  • pkcon -v refresh and pkcon -v get-updates please. Mabe packagekit is to blame for. – nobody Jul 02 '23 at 08:47
  • I’ve already uninstalled the kernels as well as associated modules and Nvidia drivers that were wrongly installed. I ran an ubuntu-drivers install too, that brought my Nvidia drivers to a more recent version (was 515, now 535). Now my system looks up to date, at least that’s what update-notifier says. I will update my question later to reflect this, but this seems to point towards ubuntu-drivers-common suggesting driver packages from non-installed kernels. Considering what I did already, do you think running those pkcon commands would still be useful from a diagnostic standpoint ? – NovHak Jul 02 '23 at 21:20
