After updates to grub2 and kernel in CentOS 7, today, systems will no longer boot in Secure Boot mode. I’m not positive, but I think grub2 is the culprit.

Is anyone else seeing the same problem?

  • Yeah, I just figured out how to query the signature of the new and previous grub image. The new one is signed with “Red Hat Test Certificate”

    [root@vagrant ~]# pesign –show-signature –in
    /var/tmp/grub2-16/boot/efi/EFI/CentOS/grubx64.efi
