--- Comment #15 from Maik Qualmann <metzping...@gmail.com> --- If the "mysql_upgrade" fails, the database may not be clean. We need to do this upgrade due to the many changes to the internal database structure with almost every new MariaDB release. Other projects that manage an internal database also do this (e.g. Akonadi). Are there any messages in the MySQL error log in the database directory?
