Same here

[shvchk]

Please provide more info, so I can test:

• OS version
• GRUB version
• How do you install the theme

[shvchk]

Was able to reproduce this issue on Ubuntu 23.04 and Fedora 38 with secure boot enabled. This is related to changes in GRUB font handling with secure boot enabled, looking for a fix.

Trying to manually load font in grub console gives this error message:

error: ../../grub-core/kern/efi/sb.c:169:prohibited by secure boot policy.

Please provide more info, so I can test:

• GRUB version
• How do you install the theme

1. Linux 22.04
2. GRUB 2
3. Using script

[shvchk]

Unfortunately this is now GRUB intended behavior: with Secure boot enabled, it doesn't load unsigned fonts, and there is no straightforward way for users to sign 🤷‍♂️ Until this is resolved upstream (try searching for "font" in GRUB dev mailing list), themes / users can't use custom fonts anymore with Secure boot enabled. There is some hope, but it doesn't seem it is going to be resolved any time soon.

I'll leave this open until upstream decides if they are willing to provide a way for themes to use custom fonts. Feel free to add more info you discover.
