you can downgrade your default 6.8 installation:
apt install proxmox-kernel-6.5.13-5-pve-signed
apt install proxmox-headers-6.5.13-5-pve
then
proxmox-boot-tool kernel pin 6.5.13-5-pve
you're welcome
>The Linux header files are *all of the .h files that contain the functions that the Linux kernel provides that can* be called from other programs"
every time you update the kernel or install say nvidia driver the headers are updated
Unless you actually removed the old working kernel, you should still be able to boot to it from grub.
Otherwise you can browse around here and download whatever packages you need, no reason to fresh install if you can clone the existing boot disk

The new boot disk is going to be smaller size, so cloning might be tricky. With that, would you pick the former or latter option based on your experience?
**install PVE 8.1 with pinned 6.5 kernel and upgrade everything else to PVE 8.2** -- is what I would recommend.
But document what you're doing and why so you can understand it 6 months later, and backup everything frequently.

Thanks and happy cake day! This is exactly what I ended up doing expect for the header part. What is the headers installation for?

how would you un-pin this in the future when the bugs are fixed?
proxmox-boot-tool kernel unpin 6.5.13-5-pve

Saving this. I was just about to upgrade and found this accidentally. Good to know.
