When using kOrganizer,it says akonadi cant start due a problem with Akonai,doing this fix the issue

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.
