Comment 18 for bug 1928010

Oh, I see that the shim packages - both amd64 and arm64 - appear to no longer contain binaries. The thing I tested successfully in Comment #11 was shim-signed, which does. I'm not sure if this change to shim is intentional or not (I don't see anything obvious in the changelog), so I'll go ahead and mark this as verification-failed across the board for now.
