[Bug 1877576] [NEW] Grub Installation failure during fresh Ubuntu 20.04 install

[James Richardson]

Public bug reported:

During vanilla install of Ubuntu 20.04, the installer says grub-
installed failed to install grub onto the partition. System was
previouslly booting PopOS 18.04 without issue.

What I expected to happen: Ubuntu 20.04 and grub to be installed without
issue

What happened instead: Ubuntu was installed, but grub didn't install
into the EFI partition (presumably because it couldn't find it?)
