Ubuntu hirsute QA-test install on
- (will be added)

Testcase was replace partition sda1 using "Something-else or Manual", replacing the last Lubuntu QA-test install performed a few days ago in the same manner without issue (regularly done).

I didn't expect any issues here.

** Expected results
- enter my user details
- install completes, asked to reboot

** Actual results
- enter my user details
- install runs, then error

"Unable to install GRUB in /dev/sda
Executing `grub-install /dev/sda` failed.
This is a fatal error"

** Notes

This system is only used for QA-testing (occasional support tests with those QA installs)
It contained two systems
- sda1 was last hirsute QA test install
- sda2 last (lubuntu) focal daily QA-test install
