Downgrade kernel from 6.8 to 6.7

[fxandrei]

So i have just upgraded to proxmox 8.2, and i have a problem with a container.
The problem is that the 6.8 kernel seems to cause a crash in some packages i use, and it seems that the previous kernel is ok (6.7).
So is there a save way to use the kernel version ?

Hi
You can in fact do that by running

apt install proxmox-kernel-<TAB><TAB>

And choose whatever kernel you want to.
Than, pin the kernel you want to use, like this:
proxmox-boot-tool kernel pin <kernel-version> [--next-boot]

Reboot

Great.
I will test this.
But for now it seems the problem i had was solved by updating the packages i was using in the container.
