Update fails when compiling nvidia-drm-drv.c:

You'll need to install a supported nvidia driver. In the thread linked below, a user found a version that worked for them:

https://techpatterns.com/forums/about3094.html

Specifically this version of the driver released on November 19th: https://www.nvidia.com/en-us/drivers/details/236036/

Otherwise, you'll need to fall back to a 6.11 kernel until Nvidia + Your Distro update drivers to support kernel 6.12.

In the meantime, I did rebuild and upload the last 6.11 kernel for Ubuntu if you need to pull a working version for your system: https://liquorix.net/ubuntu/

Thanks for your explanations. I will consider the pros and cons of both solutions, but staying at kernel 6.11 looks more stable for my machines, at the moment.
