first no boot then no updates

[bekcl88fx]

Hi everyone,

I have been using Proxmox about 6 months without any problems ( encrypted installation over Debian)
Yesterday I did update via gui, it went ok and since there was kernel update a did reboot my server.

After that it showed "Booting Proxmox VE, Loading Linux 6.8.12-5-pve..." and it is stucked there. If I remove "quiet" from the grub parameter it stucks at random line without any error message.
The server is completely frozen, keyboard not working I have to reboot via power button.
This is the same for kernel 6.8.12-5-pve and also for 6.8.12-4-pve.

If I boot older kernel - 6.8.12-2-pve, server boots up without any problem, but I am not able to do update.

I would appreciate any help to solve this

so I managed to solve it myself.

the root cause was that there was no free space in /boot. I have to manually delete 3 oldest kernels from /boot.
Then I run apt --fix-broken install and then update via gui and everything is OK now.

Hi,

I have to manually delete 3 oldest kernels from /boot.

It would be best to uninstall old kernels via apt, thereby properly removing there package and all references.
You can list all installed kernel packages using e.g. apt list --installed | grep -E '(pve|proxmox)-kernel', then uninstall old ones as you see fit.

I wanted to remove it properly, but in this case it was not possible. The /boot run out of space during update so the kernel was partially installed but missing some dependencies. When I wanted to remove kernel with apt there was error about dependencies and when I wanted to solve the dependencies there was error about no free space in /boot. So I was running in circle

btw why there is not some sort of old kernel autoremove?
