I have not tried anything yet. Figured I'd ask before I jumped in and made it worse.

Hi dehidding,

Jumping in, making it worse and then repairing is a good way to learn a lot ;-)

Click to expand...

Just as a sanity check: does the directory exist? How much free space does /boot have? Did it remove your current kernel?

Code: 
# uname -a
# ls /boot/*
# df -h /boot

Are you on UEFI or BIOS?
 
This machine is on BIOS, it's an HP DL360 G8. I've never had an issue previously running an update/upgrade, which is what threw me. An error at the end of the upgrade where the script is replacing boot files - not an area where I like to "play around" since an error can prevent the machine from booting. The machine boots from a mirrored pair of SSDs. Because it's an older machine I had to go through a few hurdles to get proxmox to install properly. Still, it's worked beautifully for the past year with no hiccups.

By coincidence I had the same update waiting for me; it ran without a hitch.

Free space certainly does not seem a problem on your system.

Have you tried re-running apt upgrade, or have it explicitly install proxmox-kernel?
 
So hearing that the update ran ok for somebody else gives me more comfort that there is not an error in the update.

And running apt update and then apt upgrade...everything finishes without issues. So my concern was overblown. Thanks for your help.
