OK I tried this again and discover shim is signed twice. Issuer: C=US, ST=Washington, L=Redmond, O=Microsoft Corporation, CN=Microsoft Corporation UEFI CA 2011 Not Before: Sep 9 19:40:20 2021 GMT Not After : Sep 1 19:40:20 2022 GMT Issuer: C=US, ST=Washington, L=Redmond, O=Microsoft Corporation, CN=Microsoft Corporation Third Party Marketplace Root Not Before: Jun 27 21:22:45 2011 GMT Not After : Jun 27 21:32:45 2026 GMT This is the same for EFI/fedora/shimx64.efi and EFI/BOOT/BOOTX64.EFI which also have the same sha256sum hashes. So maybe there isn't actually a problem other than it's confusing that there are two signatures that also have different validity periods? I'm not sure what it means. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
