operating-system: Failed to Update from HA OS 8.1 to 8.2

Describe the issue you are experiencing

Updating from HA OS 8.1 to 8.2 from the UI stops without presenting any errors on screen. Here’s a log snapshot from Supervisor:

22-06-14 17:15:25 ERROR (MainThread) [supervisor.os.manager] Home Assistant Operating System update failed with: Installation error: Failed marking slot kernel.0 non-bootable: Failed marking ‘kernel.0’ as bad: Failed to run grub-editenv: Child process exited with code 1

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

8.1

Did you upgrade the Operating System.

No

Steps to reproduce the issue

1. Once Home Assistant Update notifications appears, click on Settings and navigate to the notification
2. Hit Install and wait
3. About 2 minutes later, the “Installing” status clears up with no errors, but HA is still on old version (8.1) …

Anything in the Supervisor logs that might be useful for us?

Additional information

My host is Dell Wyse 7020. Runs HA comfortably with less than 10% utilization. My upgrades post 7.6 experience have been quite bumpy.

Going from 7.6 to 8.0. I got hit by the GRUB2 bugs and my instance had to be scraped and restored from backup. Naturally, I skipped 8.0, and updated from 7.6 > 8.1. This was fine, but anytime I reboot, GRUB defaults to “Slot A” which contained 7.6, and I had to manually hook a monitor to the box to select Slot B for 8.1 to load
