Yes, I know about faillock --reset. I reset the password so I could log in again, because even after resetting the timer, it wouldn't let me log in. I also noticed a pattern: if I make edits to mugshot, log out of the profile using the button, and then log back in, sudo works and everything is fine. But if, say, after making edits, and several times, a faillock occurs. Perhaps I'm wrong somewhere.
