Thanks for the test. It looks like we're getting farther. The error
messages here indicate that the \EFI\ubuntu\grubx64.efi on this disk is not
signed with the Canonical key. In fact, it's not signed by any key ("Empty
security header"). Can you double-check your image, and make sure to use
the unmodified grubx64.efi from the standard Ubuntu image? The *only*
change from the standard Ubuntu image at this point should be the copy of
shim.
