[Bug 1872212] Re: grub-install: Operation not permitted

[Night Train]

Yes, @Jack Christensen (jchristensen), it’s the same for me too.
I found it interesting to read the explanation given at this link:

I hope it’s useful to everyone.

Title:
  grub-install: Operation not permitted

Status in grub2-signed package in Ubuntu:
  Confirmed

Bug description:
  I'm using Ubuntu 20.04 beta, upgraded from 19.10. 
  When doing the last upgrade I got an error message from grub.

  When I run ›dpkg-reconfigure shim-signed‹ I get this error:

  Installing for x86_64-efi platform.
  grub-install: warning: Internal error.
  grub-install: error: failed to register the EFI boot entry: Operation not permitted.

  Since then I didn't reboot, for I'm afraid it won't work.
