According to your output there you should be good to go. Is your Pi showing as online now?
That looks like the end of a successful install! 
Once the Pi is back from reboot, check your Cayenne web dashboard and see if it is listed and showing as online.
Which command to start now?
YES !!!
Thank you VERY MUCH !!!
