Public bug reported:
Hello!
In my attempt to workaround Bug 1839317 I tried to install shim-signed
and enable Secure Boot. Unfortunately, shim-signed binary does not boot
for some reason (screen stay black). I want to notice that if I try to
boot just with grub-efi-arm64-signed without shim binaries on esp
(partition was cleaned up, then grub reinstalled) I getting firmware
errors regarding invalid signature. So I guess when firmware validate
shim-signed signature it is valid, but then when firmware trying to
start shim-signed it get started but for some reason silently fail.
