Solved - Failing apt upgrades

Sometime back I ran a routine update. apt update... then apt dist-upgrade

One host upgraded, rebooted, and came back online fine.
2nd identical host upgraded, rebooted, dropped to single user mode and would not mount a USB drive correctly.

Long story short, I forced grub to boot the older kernel, and that's where it sits now. Boots fine, mounts USB drive correctly, guests come online.

All subsequent updates have failed. See below:

I'm lost. Please point me in the right direction.

Hi,
it looks like you had a failed installation before:

Could you try to run apt --fix-broken install and post the output if it fails?

Both failures hint to a partial installation of proxmox-kernel-helper, please try reinstalling it:
Bash: 
apt --reinstall install proxmox-kernel-helper

To add to this. After this last failure I noticed and ran this

apt --reinstall install pve-kernel-5.15.107-1-pve

Then ran apt --reinstall install proxmox-kernel-helper again and it installed.
 
Ran pve7to8 and a failure of "FAIL: proxmox-ve package is too old, please upgrade to >= 7.4-1!" was experienced. Ran "
apt --reinstall install proxmox-ve" and now no failures.

I will reboot again and make sure the current kernel boots and report back later on.

Thank you for getting me on track. I was going cross-eyed looking at this and banging my head.
 
That did it. She booted.
