The day before yesterday, I got the error as originally reported, except I was running Kubuntu 20.04, got the updates available prompt, opened Discover, updated shim and shim-signed, waited for both the regular software update and grub update to finish, and then restarted.
I posted a question on Ask Ubuntu, then found a CentOS bug with a fix I was able to adapt to my own situation and answer my own question. If you're a bug fixer, read the first note on the CentOS bug; if you've got this same problem, read the Ask Ubuntu question and answer: https://bugs.centos.org/view.php?id=15522#c33203 https://askubuntu.com/questions/1277828/how-do-i-fix-broken-boot-after-shim-update ** Bug watch added: bugs.centos.org/ #15522 https://bugs.centos.org/view.php?id=15522 -- 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
