Hello everybody,

I'm using ROS on a ubuntu 16.04 PC. There I've got a catkin_ws with several packages in it. Some of the packages publish and subscribe topics that should be used in the network of my robot. Each package has a launch-file. All package-launchfiles are also together in one single launchfile to start all nodes together.

If I want to start the launch-file for the full system I get the following error:

roslaunch full_system.launch
... logging to /home/serva-eve/.ros/log/8d1fbfe0-0a87-11e8-9ab8-00012e8036c4/roslaunch-servaeve-ZBOX-EN1080-1080K-3993.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
Done checking log file disk usage. Usage is <1GB.

ROS path [1]=/opt/ros/kinetic/share

I could imagine, that it has to do with the environment, where my workspace has to be set. An because of that the packages can't work together.

Any help ... (more)

A good place to start is the ROS Network Setup page on the wiki. Go through that and once you come to something that you don't understand please ask a question about it. Otherwise, it's difficult to answer a question that's as broad as "How do I setup my network?"
