I am getting the following error message displayed before the

error:
../../grub-core/kern/efi/sb.c:169:prohibited by secure boot policy
That's not a file you'll find on your system. That's just
identifying where in the grub code that the error message is coming
from. As you say the grub-gfxmode command isn't working now, I
would assume that's what is causing the error message because it's
not allowed with secure boot enabled. You most likely have to stay
with the graphics mode that is initialized by the BIOS.
Thanks Samuel. Are you saying that grub command is not allowed if F37
because F37 is now booting via grub with full secure boot enabled,
whereas with the way F36 booted that grub command was honoured and
the menus and theme were displayed in that resolution with full
secure boot enabled?
That was just a guess and I think it was wrong now. I checked the
source and that error message is related to file loading. I would
have to see your config file to make a guess about what file it was
trying to load.
I backed the fix out and disabled the testing repository, which backed
grub out to 2.06.63. I did a further backout which backed grub out to
2.06.58 which supposedly doesn't have the issue, but a rebuild of
grub.cfg and reboot still displayed the message, still ignored the
specified resolution and ignored the gfxterm specification because it is
still not displaying the theme. I could try switching to the breeze them
with is supplied in the repositories.
After the boot, I issued sudo dnf upgrade --refresh grub2\* to reinstall
the offending grub version, but that installed grub 2.06.67, which was
the version in the testing repositories, so it looks like it has been
migrated to the "stable" repositories even though the bugzilla entry was
indicating they may not be up to scratch. Having gone back to this
version of grub it looks like the message is being produced for all 6
fonts the theme is loading.
Does anyone have any ideas on how to sign the fonts?
regards,
Steve
