Robot Model Error

- RVIZ Status Error No Transform
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
$ sudo apt install catkin [sudo] password for eepp: Reading package lists... Done Building dependency tree... Done Reading state information... Done Some packages could not be installed.

I'll come back to this later

Note: change to turtlebot3_ws done by create a duplicate file. To be fixed
