Comment 2 for bug 1809529

The title of this bug is certainly false. shimx64.efi consistently works on EFI systems with or without SecureBoot enabled.

I clicked on the first forum thread that you linked to, but it is a long discussion and doesn't enlighten me as to what the actual problem is that you're experiencing or why you are blaming shim for it. Please provide the complete output of the commands that are failing on your system.
