[Bug 1962678] [NEW] grub2 fails to install upon ubuntu installation

[Nikolai Gonzales]

Public bug reported:

Currently attempting to install ubuntu 20.04 alongside Windows 11 on my
HP laptop. I have tried the boot-repair service on previous installation
attempts yet still receive errors when that program attempts to repair
grub. If it is any help, here is the pastebin of the errors from boot-
repair from a few weeks ago:

https://paste.ubuntu.com/p/45dnxkjfHG/

It seems like these lines are most important:

*********************************************************************************************

grub-install --efi-directory=/boot/efi --target=x86_64-efi
Installing for x86_64-efi platform.
grub-install: error: cannot open `/boot/efi/EFI/ubuntu/grubx64.efi': Not a directory.
Exit code: 1
Refind detected on nvme0n1p1
Error: no grub*.efi generated for Ubuntu 20.04.3 LTS. Please report this message to boot.repair at gmail.com

/sbin/grub-install: error: cannot open `/boot/efi/EFI/ubuntu/grubx64.efi': Not a directory.
--no-nvram exit code: 1 Please report this message to boot.repair at gmail.com

*********************************************************************************************

I will continue to try different fixes on my end to install Grub, but it
seems like an actual bug in the ubuntu/grub installer for EFI systems.

Thank you!
Nikolai
