Comment 2 for bug 1368124

This error message is due to a file that has been re-located from the server package to the client package.

To recover from this, run 'sudo dpkg -r mariadb-server-5.5', then run the 'sudo apt-get upgrade' (or maybe 'sudo apt-get install -f') and then finally 'sudo apt-get install mariadb-server'. The removes will not remove any data or configuration, so after the last command your MariaDB server should be fully ready to continue as it was before.
