After PVE 7.4 upgrade, booting could not find vmlinuz-5.15.131-2-pve

[MikeC]

I performed a standard update on my 7.4 proxmox server to get the latest deb11 patches.
I did not see any errors during the upgrade, but after rebooting the box for the new kernel, I got this error:

Booting `Proxmox VE GNU/Linux`
Loading Linux 5.15.131-2-pve...
error: file `vmlinuz-5.15.131-2-pve' not found
Loading initial ramdisk...
error: you need to load the kernel first

From the boot screen I was able to select and boot using the previous kernel (5.15.131-1-pve), even though the new kernel showed up in the list along with the older kernels.
Not sure why it couldn't "find" it.

* apt update does not show anything needing to be installed.
* pveversion shows: pve-manager/7.4-17/513c62be (running kernel: 5.15.126-1-pve)
* All containers started up fine.

How would I fix this problem?

Hi,

I performed a standard update on my 7.4 proxmox server to get the latest deb11 patches.

First of, how did you exactly perform the upgrade, e.g. what commands did you use, steps taken etc.?
Second, Proxmox 7.4 (as well as Debian Bullseye) will go EOL this year, so you should consider upgrading to 8.1 soon - just FYI.

How would I fix this problem?

Can you please post the output of pveversion -v and ls -la /boot?
This should help narrowing it down.

Hi. Thanks. I did the upgrade through Proxmox's Upgrade link as opposed to apt update.
