The choice of python was simply rooted in my familiarity with it while I am sure there would be better alternatives than python for this task. The goal of this script was to install ROS onto the machine running the script and also setup the catkin environment. Directions can be found here and here, respectively. The script as it currently sits is as follows: subprocess.call(["sudo", "sh", "-c", "'echo \"deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main\" > /etc/apt/sources.list.d/ros-latest.list'"]) subprocess.call(["sudo", "apt-key", "adv", "--keyserver", "hkp://ha.pool.sks-keyserver.net:80", "--recv-key", "0xB01FA116"]) subprocess.call(["sudo", "apt-get", "update"]) subprocess.call(["sudo", "apt-get", "install", "ros-kinetic-desktop-full", "-y"]) subprocess.call(["sudo", "rosdep", "init"]) subprocess.call(["rosdep", "update"]) subprocess.call(["echo", '"source /opt/ros/kinetic/setup.bash"', ">>", "~/.bashrc", "source", "~/.bashrc"]) subprocess.call(["sudo", "apt-get", "install", "python-rosinstall", "-y"]) mkdir_p(os.path.expanduser('~') + "/catkin_ws/src") subprocess.call(["(cd "+ os.path.expanduser('~') + "/catkin_ws/src)"]) subprocess.call(["(cd "+ os.path.expanduser('~') + "/catkin_ws && catkin_make)"]) subprocess.call(["(cd "+ os.path.expanduser('~') + "/catkin_ws && source devel/setup.bash"]) When the script is currently runs it errors out with the error: Traceback (most recent call last): File "setup.py", line 46, in
