Revision history [back]

You should build all necessary packages from source. In the case of turtle sim first download it to ./src folder of your workspace i.e. ~/ros_ws/ then build it. To summarise the procedure

cd ./src    
git clone https://github.com/ros-gbp/ros_tutorials-release.git
cd ..
catkin_make

or

catkin_make_isolated --install --install-space /opt/ros/groovy

the last line will install packages to the folder where the rest of the packages are installed.
