Hi all,

I tried to upgrade my hypervisor just as usual by apt update and apt dist-upgrade followed by reboot commands. This was a minor upgrade from 8.0.x to 8.1. But the server didn't boot up. After connecting to KVM console I've noticed that it's stuck on boot.

I had some kernel versions installed and tried to boot into different kernels. I couldn't boot into 6.x kernels anymore: 6.5 was stuck at RPCbind Server Activation Socket step, and the previous kernel 6.2 ended with Kernel Panic. The only version I could boot into was 5.15.108.1, all VMs are up and running, and the PVE version is shown as 8.1.3 in GUI. After some investigation I figured out that the /boot partition was 100% full and this means that I had a corrupt kernel upgrade.

I tried to do the following steps.
1. apt autoremove
2. apt --fix-broken install
3. update-grub
4. update-initramfs -u

But no luck after reboot, I cannot boot into 6.5/6.2 kernel. I tried to reinstall 6.2 kernel:
1. apt reinstall pve-kernel-6.2.16-3-pve
2. update-grub
3. update-initramfs -u

Can anyone give some advice how can I correctly upgrade to 6.5 from 5.15 kernel?

One more thing I tried:

- Remove all 6.2/6.5 kernels with apt remove proxmox-kernel-6.xx.x-pve
- Install them from scratch: apt install proxmox-kernel-6.5.11-5-pve, apt install proxmox-kernel-6.2.16-19-pve.

Now I've got the following grub menu:

But I'm still unable to boot into 6.2.16-19 or 6.5.11-5 kernels. The screenshot below is for 6.5 kernel boot attempt:

But I can only boot into 5.15 kernel.
 
eyeless - any traction on this issue?
I ran into a similar issue last night - can't boot at all, says it's missing an initram file, and then completely freezes.

Open ears for anything that you tried to do, to fix your issue.

Many thanks.
