Hi there, I am using Ubuntu 10.10 32bit and I am trying to get to know ROS. After I had some issues with the installation (sudo apt-get install ros-cturtle-base has unresolved dependencies even though my repositories allow "restricted," "universe," and "multiverse) I installed one package after another. Now I am stuck with the tutorial Simulating One Robot in Stage. The command "rosrun teleop_base teleop_base_keyboard base_controller/command:=cmd_vel" does not work for me because the system cannot find teleop_base. I also cannot find the package. What can I do? Thank you very much. With kind regards, Martin
