Your error is different than what is discussed in this thread. Therefore I suggest in the future create a new thread or a question on answers.ros.org.

i thought we are posting ros2 issues in ros discourse. And also, as this topic is related to ament build tests which i created earlier so I linked this issue to this thread.

Regarding the error message: it looks like you are mixing a newer version of rmw_fastrtps_cpp with an older version of rmw. This is not supported. Either stick two both packages from e.g. the latest release or use both packages from the current default branch.

I did `sudo apt-get remove ros-ardent-*` and also removed my workspace and then downloaded and reinstalled everything back. How do I solve this again? I think old versions Screenshot from 2018-02-02 11-22-19have stayed in. Please help, it has stopped all my development in ros2 now.

I have these installed :
