Both MySQL database core client and MySQL Server packages, needs to be the same version.
MySQL Client 5.5 and MySQL Server 5.5 are the current “best” versions of these packages in Ubuntu 14.04 as determined by the package maintainers, however, if you need to work with Magento 2, its mandatory to install at least MySQL 5.6
