Multiple errors in chapter 2

I’m kinda stuck in chapter 2-Mapping. Your example/exercise 2.2 starts with “ros2 launch turtlebot3_cartographer”. How should that work? There is no package in my ros2_ws.
So I started “cheating” by sourcing your install workspace “/home/simulations/ros2_sims_ws/install/setup.bash”. With that I could run the cartographer BUT the next command: “ros2 run turtlebot3_teleop teleop_keyboard” crashes, with a "KeyError: ‘TURTLEBOT3_MODEL’ ".

Now I’m confused why no one else reports these problems !?
Have you executed the course once?

Best Regards

Btw there is a “spelling error” (missing L) in a call in chapter one “source instal/setup.bash”
