Ubuntu 22.10 and the 5.19 kernel are now using a revoked SHIM/key, the upgraded key would have been on your system prior to revocation if you'd performed the release-upgrade prior to EOL; the delay may have complicated your issues, and support maybe your fix.
Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug.
I suspect a Support site would be more appropriate, eg. https:/ /answers. launchpad. net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http:// loco.ubuntu. com/ or asking at https:/ /askubuntu. com or https:/ /ubuntuforums. org, or for more support options please look at https:/ /discourse. ubuntu. com/t/community -support/ 709
