First you must have the ROS repositories which contain the .deb for catkin_tools:

$ sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu `lsb_release -sc` main" > /etc/apt/sources.list.d/ros-latest.list'
$ wget http://packages.ros.org/ros.key -O - | sudo apt-key add -

Once you have added that repository, run these commands to install catkin_tools:

$ sudo apt-get update
$ sudo apt-get install python-catkin-tools
