That means you have not compiled your workspace correctly in order for the system to find the package services_quiz. Check the instructions on how to make a package, compile and source your workspace.

If you have done or redone everything correctly, try:

cd ~/catkin_ws
rm -rf build/ devel/
source devel/setup.bash
