grub-install failed during reinstall

[Malachi de AElfweald]

This machine was previously running 18.04. I decided to replace it with 21.04 (using the ISO via USB) rather than doing an in-place upgrade.

The Ubiquiti installer gets to the grub-install step then fails with:
```
Executing grub-install /dev/nvme2n1 failed
This is a fatal error
```

TBH I would have expected that it should have been something like /dev/nvme2n1p1 since that was the vfat partition it created.

I tried enabling the same kernel configuration I used to finally get 18.04 to install a couple years ago, but with the same end result.

I finally managed to get it to install (using minimal) on the 6th try. The
only thing I did differently was watch the logs and not click any buttons
if the logs showed that something was in progress.
