[SOLVED] Updating Proxmox VE kernel. How to ?

[kast0r]

Hi,

I read that there was kernel version 5.15.35 which had a fix for Intel Alder Lake processors. (I own an i5-12600K).

What is the procedure to update the kernel? Right now I'm on 5.15.30

You just update PVE like normal and reboot the server to the new kernel package can take into effect. If there is no newer kernel package available, you might want to test out another repository. There is for example a test repo you could add: https://pve.proxmox.com/wiki/Package_Repositories#sysadmin_test_repo

But of cause, newer also means less stable and less well tested. So I would always try to stick with older versions unless you really need it to fix something important.

What is the procedure to update the kernel? Right now I'm on 5.15.30

apt update
apt dist-upgrade
reboot

edit: you might also have to adapt your apt repo sources list [0]
