Hi,
I am sorry for duplicating some questions but I am totally new and I just cannot find the right answers 
So if anybody help, I would be most gratefull.
- I have created my own docker file where I want to run the simulation of quadrocopter within gazebo11. Everything seems to be installed and ok, but when I run the sim_vehicle.py it starts and then it kills everything with message mavproxy exited. And I dont know why, I checked and mavproxy was installed, but it was not found initialy so I have updated ENV PATH with the location of mavproxy. It is found after this, but it does not work.
- If I run the sim_vehicle.py --no-mavproxy it seems to work and I am even able to connect to vehicle on tcp 5760, but the vehicle will not work since some preflight failures. Can I use this aproach to start simulation without mavproxy? Or is the mavproxy needed to make it work, to connect all the sensors from the gazebo plugin and so on?
- I would expect that I need to run it with mavproxy and connect to the vehicle on udp port, something like 14550?
I am on ubuntu 22.04.
Thank you in advance. Lukas
