Upgrading MySQL 5.5 to MariaDB 10.0 on Ubuntu 12.04.3 LTS

I couldn’t find instructions for upgrading from MySQL 5.5 to MariaDB 10.0 on Ubuntu 12.04.3 LTS. Fortunately, MariaDB and Ubuntu didn’t let me down, and provided a smooth installation process. Here’s a log of my console session in case it helps anyone else out there!

Excellent resources used:
