The repository linking from [http://www.ros.org/wiki/groovy/Installation/Raspbian](http://www.ros.org/wiki/groovy/Installation/Raspbian) was outdated, as pointed out by po1. It has been updated to contain version 0.10.20 and this solved the issue. I would like to thank everyone that contributed for their help! Please keep sharing!
