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

[Artur]

Just happened for me too, on a 20.04 kubuntu system.

apt upgrade output:
Setting up grub-efi-amd64-signed (1.142.9+2.04-1ubuntu26.7) ...
Installing grub to /boot/efi.
Installing for x86_64-efi platform.
grub-install: warning: Internal error.
grub-install: error: failed to register the EFI boot entry: Operation not permitted.

Window popped up too. Manual grub-install fails in the same way that apt installation does:
# grub-install 
Installing for x86_64-efi platform.
grub-install: warning: Internal error.
grub-install: error: failed to register the EFI boot entry: Operation not permitted.


According to /var/log/apt/history.log those grub packages were upgraded:
grub-common:amd64 (2.04-1ubuntu26.6, 2.04-1ubuntu26.7)
grub2-common:amd64 (2.04-1ubuntu26.6, 2.04-1ubuntu26.7)
grub-pc:amd64 (2.04-1ubuntu26.6, 2.04-1ubuntu26.7)
grub-pc-bin:amd64 (2.04-1ubuntu26.6, 2.04-1ubuntu26.7)
grub-efi-amd64-bin:amd64 (2.04-1ubuntu26.6, 2.04-1ubuntu26.7)
grub-efi-amd64-signed:amd64 (1.142.8+2.04-1ubuntu26.6, 1.142.9+2.04-1ubuntu26.7)

Did not yet try to restart the PC either.

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.
