I have installed gazebo garden on Ubuntu 22.04 per the instructions at :
I then installed the ardupilot_gazebo plugin as per :
When the following is run I get the correct simulation with the vehicle on a runway.
gz sim -v4 -r iris_runway.sdf
When I then run the sim vehicle it deploy correctly, and I can arm and takeoff.
sim_vehicle.py -f gazebo-iris --map --console
However, the gazebo sim vehicle is not responding appropriately, ie, there is no arm and takeoff.
I am guessing the environment has not been configured correctly and looking for any suggestions.
