Ubuntu 12.04’s included libssl is incompatible with the default mysql verison provided. This isn’t how to fix that, but a warning not to try. Just use 14.04 LTS.

If you did set up SSL on a 12.04 server, you’ll likely run into issues exporting your database. If you get errors like these, just disable SSL.

Commenting out ssl-ca, ssl-cert, ssl-key and ssl-cipher lines in your /etc/mysql/my.cnf file and restarting the service with sudo service mysql restart should allow you to export again.
