after upgrade, unable to boot

[why-be-banned]

After I executed the command apt upgrade && reboot, I can't start pve, I get this error:




If I select kernel 6.8.12-4-pve, it can boot.




As a temporary measure, I switched to the old kernel "pve-efiboot-tool kernel pin 6.8.12-4-pve".

What should I do ? thx.


After upgrade:

apt upgrade && reboot

You should be using apt-get dist-upgrade, as shown here. Using apt update may ( break | have broken ) your system.

Alternatively, you could use the Proxmox provided command (wrapper): pveupgrade (since ver. 3.1), which also uses the above command - with more info/advice.
