Proxmox on Debian won't upgrade to latest kernel

[chicagonyc]

Hello, I'm running Proxmox 8.2.2 running on kernel 6.5.13-5-pve. I install proxmox after I installed Debian, and I haven't had issues until a few days ago.

I ran apt update && apt upgrade recently, and got the following pile of errors. It looks like something related to Nvidia. I am running an Nvidia Quadro M2000, an older card but according to Debian, Nvidia 525 should work. Perhaps a conflict with kernel 6.8.4?

So the upgrade doesn't work. I tried rebooting, and oddly, there was a 6.8.4 entry -- if I select this, the boot hangs. But if I use advanced options to go back to 6.5, it does boot successfully.

I'm attaching the output of Nvidia-smi.


Any ideas?

I think I fixed the problem by first purging the nvidia drivers according to this post. Then I booted into 6.8.4 without a problem.
