I started first in my Linux terminal by placing myself in the raspberry pi card of my robot with the ssh command ubuntu@$192\mathrm{.}168\mathrm{.}28\mathrm{.}24.$ Then I tried to connect my controller to the robot with the different commands in the capture of screen that I sent you. But when I use the final: connect command to establish the connection, it does not work with its errors connected: yes and after no$.$ This makes the controller flash and turns it off without the connection is established. I am on ubuntu $20\mathrm{.}04.$ Can you please help me to resolve this error so that the connection is established?
