** Description changed: This package is missing the usr.sbin.mysqld AppArmor profile that ships - in mariadb-server-10.0 and mysql-server-5.7. As a result, - /usr/sbin/mysqld is unable to create files in /var/lib/percona-xtradb- - cluster/, and the service is unable to start. + in mariadb-server-10.0 and mysql-server-5.7. + + As a result in case of a pxc being installed on a server that previously + had either of those packages installed, /usr/sbin/mysqld is unable to + create files in /var/lib/percona-xtradb-cluster/, and the service is + unable to start.
