Just encountered this problem when trying to setup a fully encrypted system. I rebuilt the grub2 package with the changes listed in the first comment and tested in VirtualBox in UEFI mode and it does work.
You can't simply copy the modules to the ESP partition because it a) won't work with secure boot and b) grub seems to be hardcoded to try to load them from the /boot/grub/ directory which isn't accessible at that point in the boot process and there doesn't appear to be a way to specify them manually. Can these extra modules please get included in the grubx64.efi binary? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1565950 Title: Grub 2 fails to boot a kernel on a luks encrypted volume with Secure Boot enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1565950/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
