Proxmox Kernel Update Question

[hand363]

Hello,

Today, I went to update my Proxmox (no-subscription) cluster currently running 6.8.8-3-pve, and noticed it had two different kernel updates (6.5.13-6-pre & 6.8.8-4-pve) at the same time.
Could someone explain why I have an update to an older kernel?
Does Proxmox keep the older kernel as a fail over in case a bug in the newer kernel comes out?
Does the Enterprise repo do this?

Thanks!

It's a security fix, which typically affects multiple kernel versions. You can read the change log in the Proxmox GUI.

Does the Enterprise repo do this?

Probably, yes but I uninstalled proxmox-kernel-6.5 since 6.8 is the new default.

Run

apt autoremove --purge

. It will probably remove old kernels but keep the latest two so you still have a fall back if the new one is a problem.
