Package: src:shim
Version: 15.7-1
Dear maintainer,
I have an HP Elitebook 2570p laptop with flawed UEFI firmware which
ignores EFI boot variables in NVRAM for booting and boots from the
removable media path by default. So I installed a copy of GRUB in the
removable media path with:
# grub-install --force-extra-removable
Secure boot is enabled in UEFI/BIOS settings.
For a test I wanted to disable secure boot validation in shim with:
# mokutil --disable-validation
and rebooted. At boot, the following error is displayed:
Failed to open mmx64.efi - Not Found
Failed to load image: Not Found
Failed to start MOK Manager : Not Found
and the laptop shut down after a couple of seconds.
Indeed /EFI/BOOT on the EFI system partition contains only BOOTX64.EFI,
grubx64.efi and fbx64.efi.
Now the same happens every time I reboot from the removable media path,
either on the hard disk or on a USB drive with a Debian installation image.
Not sure which software is to blame here.
- grub-install which does not install the MOK manager into the removable
media path ?
- shim which shuts down the laptop instead of just ignoring the
validation change request if it does not find the MOK Manager ?
