“The Akonadi personal information management service is not operational” when I try to use KOrganizer or KJots.

The Akonadi personal information service is not operational

Try from terminal: rm -r ~/.local/share/akonadi/ and restart KMail. Or make a backup of that folder … so you might keep some of the older data …

Akonadi can't launch mysqld after update of mariadb

This seems to be related to apparmor. sudo aa-complain /usr/bin/akonadiserver fixed it for me. Once the issue is fixed, or if this doesn’t help in your case, you should issue a sudo aa-enforce /usr/bin/akonadiserver, to reactivate apparmor.
