turtlebot teleop and follower apps do not work

edit

Hello

I just received my Turtlebot 2/Kubiki base. It comes with Groovy pre-installed in the ASUS Laptop. I wanted to start the two demo applications

So, I did

roslaunch turtlebot_teleop keyboard_teleop.launch

and roslaunch turtlebot_follower follower.launch As in Tutorial, I opened an ssh from my PC and run the launch files.

For "roslaunch turtlebot_teleop keyboard_teleop.launch" I get the following error:

IOError: Errno 13 Permission denied: '/home/turtlebot/.ros/rosdep/sources.cache/index'

and for "roslaunch turtlebot_follower follower.launch" I get the following error:
