Not sure but I think this may have caused my apt upgrade to fail

After installing this, I started upgrade from web ui, the apt hook seems to execute and causes the web console to crash. I think this caused my boot/kernel/grub upgrade to crash midway because when I restarted the machine, grub could not find a kernel to boot from.

On the other node where this wasnt installed the upgrade and reboot worked.

Yeah, I think this did the same for me. I haven't rebooted yet but I'm honestly quite worried to...

I think you can continue the apt update process if you run it from ssh:
dpkg --configure --pending
and maybe
apt-get --fix-broken install

It says there are no packages left, so hope everything ended up being installed just fine. My apt log looks worrying though, with it showing it's running the pve-nag-buster followed by "log ended"... Maybe it was the last thing left to-do and I was spared.

For now I've uncommented the pveproxy restart from the nag-buster, I'll just do this myself
