As the new ISO Maintainer, the TurtleBot ROS PPA has changed.
ROS is not yet configured to start automatically due to new multimaster options in hydro. Please see documentation for more information. To enable automatic startup with a minimal (non-multi-master) configuration, install ros-system-daemon-hydro and turtlebot-indicator-hydro from the PPA.
apt-get update apt-get install ros-system-daemon-hydro apt-get install turtlebot-indicator-hydro
