Robot Model Error

in new Terminal
$ launch turtlebot3_bringup turtlebot3_model.launch Command 'launch' not found, did you mean: command 'launchy' from deb ruby-launchy (2.5.0-3) command '0launch' from deb 0install-core (2.16-2) command 'launchn' from deb csmith (2.3.0-6build1) Try: sudo apt install <deb name>
Or bring up the Turtle3
source scripts/bringup.sh
Or maybe just: To be tested (This must be pretty much the same as doing the bringup script
ros2 launch turtlebot3_bringup robot.launch.py

Modify the Waffle Model
Create the dev tree
I have forgotten how to do this
mkdir -f edc_ws/src
I think
cd edc_ws/src
This didn't work
$ catkin_make -j2
Command 'catkin_make' not found, but can be installed with:
sudo apt install catkin
This didn't help

This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

I'll come back to this later
