[Bug 2043907] Re: Memtest gives "bad shim signature" error

[Richard Henschel]

I am running 24.10 and the previous workaround would give me no shim
error and would immediately return back to the boot menu.  I forced a
phased grub update on an HP Victus 15-fb1XXX and memtest I had
previously signed as previously now works fine.

sudo apt --with-new-pkgs upgrade grub-efi-amd64  grub-efi-amd64-bin
grub-efi-amd64-signed  grub-efi-amd64-unsigned

I also forced the above on an ancient Asus 500A which grub could not
boot Windows 10 in 24.10 and now that also works.  The old Asus would
run memtest without signing because it did not have EUFI secure boot on.

Title:
  Memtest gives "bad shim signature" error

Status in memtest86+ package in Ubuntu:
  Confirmed

Bug description:
  when you select memtest from the Grub menu with Secure boot enable you
  get the error of "Bad Shim Signature" I should not need to disable
  secure boot just to run this test, which then opens up the system for
  other security issues...
