I recently re-installed my wife's XUbuntu 22 machine. Previously we used the NVidia driver package from the NVidia website, especially after a bit of a f&%k up last year where the official repo version broke due to broken dependencies.

This time I thought I would give the repo version another go, especially since my wife is scared of re-installing the graphics drivers after a kernel update - and it is a real nuisance.

As per the guide I found online I ran the command sudo ubuntu-drivers autoinstall. The result was:

Traceback (most recent call last):

I manually installed the 515 drivers repo package, but it does not seem to include the 32 bit drivers, and now Steam, among other things, doesn't work.
