[Bug 1991404] Re: Error installing grub to /dev/sda

[Brian Murray]

I think this is the important part in the log file and I think it is
something with your EFI firmware or some words like that.

The python traceback isn't really useful here.

Title:
  Error installing grub to /dev/sda

Status in ubiquity package in Ubuntu:
  New

Bug description:
  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.
