Bug Description
The stock grub config does the following:
if [ x$feature_
font=unicode
else
[...]
fi
if loadfont $font ; then
[...]
'loadfont unicode' fails in the SecureBoot EFI image with this error:
error: file `/EFI/ubuntu/
From what I can tell, this is because grubx64.efi (from debian/rules) is built with -p /EFI/ubuntu, but grub-install copies the font to /boot/grub/fonts (which of course is not on the EFI system partition). In the non-SB image generated by grub-install, the prefix is set to /boot/grub, so there's no problem; but for the SB image, we don't know where /boot/grub will be. Either grub.cfg has to be changed to search for such files in the SB case, or the fonts (and locales) need to be installed to /efi/ubuntu and not just to /boot/grub.
