[Bug 1991404] [NEW] grub-install: error: failed to register the EFI boot entry: Input/output error.

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Matthieu Clemenceau (mclemenceau):

When running the installer, grub fails to install to /dev/sda with the
following error: "grub-install: error: failed to register the EFI boot
entry: Input/output error."

I have confirmed /dev/sda is the correct target device. A 22.04.1
installation on the same hardware works fine. The same crash occurs
regardless of secure boot being enabled/disabled.
