Using NVIDIA Jetson Nano with ROS - Setup Issue

I’m taking the subject course and need help to setup the Ignisbot on the Jetbot. My Jetbot is up and running ok, but I can’t find good instructions to install the scripts on the on the Jetbot. The instructions in this page don’t work unless I’m doing something wrong. https://i-0823f0105a6f5d98c.robotigniteacademy.com/f36e0ae4-fbe6-4430-984a-39d2b3bbcf1d/jupyter/notebooks/ignisbot_notebooks/ignisbot_course_assembly.ipynb

Can someone help me?
