[SOLVED] kernel 4.15.10-5 won't boot

[BuildTheRobots]

After doing an `apt update` and then an `apt upgrade` my proxmox server no longer boots.
Old kernel (which i can manually select and boot from) is 4.15.10-1.

There is no subscription, so the updates were from pve-nosubscription.

The hardware is a HP DL380p G8.

This is easily reproducable for me, i just need to reboot and select the -5 kernel revision.

Any thoughts or advice would be appreciated. I know nosubscription is unsupported, but this seems like an unexpected breakage.

Looks like it was a false report.

After rebooting from the old kernel I tried removing the newer revision so the system wouldn't try booting from it again.

Apt informed me that "E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.". Running that caused it to reinstall the kernel which it could then successfully boot from.

It looks like my previous `apt upgrade` didn't work or didn't fully commit to disk - which is odd, because it was an `apt upgrade && sync && reboot` so it really should have flushed.

Apologies for the false report, please ignore.

Proxmox guys have written everywhere to never use apt upgrade with proxmox, but always use apt dist-upgrade.
But I do think they should append this information to the /etc/motd file at install.
