The upgrade process failed to properly upgrade mysql. I am not an expert in mysql, so I don't really know what went wrong. I tried to start knotes, and got a blank note, where there should be stuff. The output of starting it from a terminal looks like this:
Akonadi (which knotes needs) won't start, and evidently has something to do with mysql not starting. Apparently mysql_upgrade no longer exists, and I really don't know enough about mysql to understand what the results from searching are telling me to do -- meaning, nothing I have found works.
systemctl status mysql.service says this:
