I just started the Unit 3 Rosject today. I am stuck on the first 2 command lines:
source ~/simulation_ws/install/setup.bash
not found: “/opt/ros/foxy/local_setup.bash”
then:
ros2 launch turtlebot3_gazebo main_turtlebot3_lab.launch.xml
[INFO] [launch]: All log files can be found below /home/user/.ros/log/2024-03-07-04-47-30-289777-3_xterm-6416

I had to Ctrl-C at the end to return to the CLI prompt.
I then modified the simulation_ws/install/setup.bash to source from humble instead of foxy, but the simulation launch got the same result.
Any idea how to fix this?
