@33thou actually, I think that I didn’t try it as I switched to C++ tutorials on reaching this step:) I hope to get back to ROS2 in few weeks. Sorry, I don’t know how to check colcon now without spending too much time.
Overall it worked, with some stability issues and some problems with labels and icons on buttons in GUIs.
I also tried to run Ubuntu via VirtualBox on MacOS Catalina. It worked but was extremely laggy when running 3D probably due to lack HW acceleration and I wasn’t able to configure VirtualBox to make things smoother.
