The following changes solved two problems: Firstly, the environment variable LD_LIBRARY_PATH is deleted by Ubuntu for security reasons. Additional paths have to be added to a new file in the directory /etc/ld.so.conf.d For example by doing sudo gedit /etc/ld.so.conf.d/ros2.conf and adding the line: /home//ros2_install/ros2-linux/lib Replace with your own username. and executing sudo ldconfig Furthermore, one package was missing: sudo apt-get install libpocofoundation9v5 ----------------------------------------- Now I get a different error message: ufechner@tuxedo:~$ talker terminate called after throwing an instance of 'std::runtime_error' what(): could not create publisher: type support not from this implementation, at /home/rosbuild/ci_scripts/ws/src/ros2/rmw_fastrtps/rmw_fastrtps_cpp/src/functions.cpp:782, at /home/rosbuild/ci_scripts/ws/src/ros2/rcl/rcl/src/rcl/publisher.c:81 Aborted (core dumped) ufechner@tuxedo Any idea, how to fix this?
