Public bug reported: This occurred after I rebooted after an update on April 23 2018. After the update, I was prompted to create a password for something regarding UEFI secure booting, and the prompt said I would be asked for this password when rebooting. When I rebooted, however, I was not asked for the password, and had to force a shutdown. I booted normally next time, except for receiving this error message. I don't know for certain if these events are related.
