          Description

          MariaDB on Power8 Ubuntu correctly depends on the Advance Toolchain runtime but when trying to install, apparmor prevents mysqld from loading the libraries.

          I was under the impression that the /etc/apparmor.d/usr.sbin.mysqld disabled apparmor for MariaDB, and that file is in place on that host, but maybe there's something with the runtime that is interfering.

          Snippet from the syslog:

                I just spun up a new IBM P8 Ubuntu image and tried installing MariaDB and it worked. So it may be that it was a fluke.
