Comment 25 for bug 1821630

Thanks, that looks like the standard set of Microsoft-issued revocations, with two differences:

 - listing a revocation of the rather unlikely hash of 0000000000000000000000000000000000000000000000000000000000000000
 - the revocations are listed as not having been issued all by the same key

I don't know what that all means, but it doesn't look like this explains the failure to boot Ubuntu's shim.
