Dear all I am trying to install ros on a freshly installed ubuntu maverick. I did this already twice successfully on other machines, but now I the installation seems to be broken. Please forgive this perhaps rather naive question from a industrial designer with little programming experience who is overwhelmed with the potential of ROS, openni and kinect since only one week. You guys do a very important work and I am deeply impressed by the whole ros project. Kind regards Mischa mischa@ubuntu:~$ sudo apt-get install ros-cturtle-base Reading package lists...
