Which image are you using, is it our Raspbian for Robots image. It might be easier to get started with it. The instructions are here.

If you are using your own image, did you follow the guidelines to install BrickPi python lib here.

i typed in sudo apt-get update and sudo apt-get upgrade in the run field but nothing is happening :stuck_out_tongue: @karan
yes i am connected to the internet on the raspberry pi

@brynjar: Can you try using our image from the link above and send a few screenshots of the problem you are getting.
