cannot launch node of type [rocon_interactions/interactions_manager.py]

edit

I'm new to the turtlebot and have setup both my workstation and the turtlebot as described in the tutorial. Both machines are running Ubuntu 14.04 and Indigo Igloo. I've been dashing my head against some errors for a while and haven't found any similar posts on the forums. If anyone has suggestions I'd appreciate them.

When I run on the turtlebot:

roslaunch turtlebot_bringup minimal.launch

and on the workstation:

rqt -s kobuki_dashboard

to bringup the dashboard I can see the colour of the battery, warnings, and other features along the top. However, the content is grey and I get errors and warnings as follows:
