This means that you don't have the latest ROS2 crystal installed on your system.

[LanderU]

To clarify the problem, one week ago the OR released a new patch (patch3) for crystal. This patch comes with some improvements. Could you please make sure that you've the latest version available on your system. If you already have ROS2 installed on your system, you can simply update it using apt install ros-crystal-ros-base.

@LanderU Thank you very much. I will give it a try.
