LP:905712 - rpm upgrade from 5.2.9 broken

The following error is produced in %pre. Looks like you're comparing Packager to Vendor.

******************************************************************
A MySQL or MariaDB server package (MariaDB-server-5.2.9-102.el5) is installed.

The current MariaDB server package is provided by a different
vendor (MariaDB (http://mariadb.com/)) than Monty Program - http://www.montyprogram.com/. Some files may be installed
to different locations, including log files and the service
startup script in /etc/init.d/.

A manual upgrade is required.

• Ensure that you have a complete, working backup of your data and my.cnf
  files
• Shut down the MySQL server cleanly
• Remove the existing MySQL packages. Usually this command will
  list the packages you should remove:
  rpm qa | grep -i '^mysql'

You may choose to use 'rpm --nodeps -ev <package-name>' to remove
the package which contains the mysqlclient shared library. The
library will be reinstalled by the MariaDB-shared package.

• Install the new MariaDB packages supplied by Monty Program - http://www.montyprogram.com/
• Ensure that the MariaDB server is started
• Run the 'mysql_upgrade' program

This is a brief description of the upgrade process. Important details
can be found in the MariaDB manual, in the Upgrading section.
