Same problem here.

I think we were bitten by this known Debian Bug:


"Wrong prefix directory hardcoded in signed GRUB image"

Signed grub assumes that the initial grub.cfg is in EFI/debian/grub.cfg
and not in wherever grub-install put it (usually EFI/devuan/grub.cfg or

You can verify this by entering "set" on the grub command line and
checking the default value of the "prefix" and "root" variables.

Workaround for me is to manually enter

configfile (hd2,gpt1)/EFI/devuan/grub.cfg

every time I boot my machine.
