Hi Kirila, How did you install ROS? You may need an updated install to get pr2_gazebo. Ken On Mar 22, 2010 7:31 AM, "Kirila Adamova" wrote: Hello, I recently started working with ROS. In the beginning I had no problem using rosdep and installing packages, but now I started getting the following message: kiki@kiki-laptop:~/ros$ rosdep install pr2_gazebo Warning: could not identify ['pr2_gazebo'] as a package Usage: rosdep [options] ... rosdep: error: No Valid Packages listed Could anybody give me a clue what I am missing here?
