It’s not clear whether you installed 4.2.19? You have to do it manually: https://www.nomachine.com/SU04L00104
Additionally, it is not clear what you are running on the server side. A similar problem is reported here: https://www.nomachine.com/forums/topic/no-mouse-cursor-on-ubuntu
If it is the same problem, I suggest you participate in that topic.
