Bug description:
  I have not fully investigated.
  Got an unexpected notice for a partial upgrade.
  Concerned that this might be FS corruption.
  Not sure at this point.

  During partial upgrade shim-signed gave error and got notice after reboot.
  efi seems to work correctly - I have dual boot.
