Ok, that log file shows no changes to the shim-signed package version installed.
There is an update to grub, which would trigger re-running grub-install, which would install the current shimx64.efi to your ESP. I don't know why you would not have had an up-to-date shimx64.efi on your system previously, unless you had manually changed the contents of the ESP. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867092 Title: Failed to set MokListRT: Invalid Parameter To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1867092/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
