CARLA version:0.9.14 Platform/OS:Ubuntu Problem you have experienced:Exception thrown: bind: Permission denied [system:13 at ../boost-1.80.0-c8-install/include/boost/asio/detail/reactive_socket_service.hpp:161] What you expected to happen:Resolve this issue Steps to reproduce: Run this file: https://github.com/praveen-palanisamy/macad-agents/blob/master/src/macad_agents/baseline_agent.py Hi, I am working on Multi-agent reinforcement learning in CARLA and I am trying to run this file.

https://github.com/praveen-palanisamy/macad-agents/blob/master/src/macad_agents/baseline_agent.py

But I got this error: Initializing new Carla server... Running simulation in single-GPU mode LowLevelFatalError [File:Unknown] [Line: 136] Exception thrown: bind: Permission denied [system:13 at ../boost-1.80.0-c8-install/include/boost/asio/detail/reactive_socket_service.hpp:161] Signal 11 caught.

Server got started and crashed suddenly. How to resolve this.

Apart from this file server is working fine.

Hi, try to run

sudo chmod 755 /path/to/carla

to make sure the permissions are right.

If that didn't work, you can look if the default Carla ports are used.

sudo lsof -i:2000
sudo lsof -i:2001
sudo lsof -i:2002

Hi, I'm facing this issue too, the Carla version that I've installed is 0.9.15 on Ubuntu 22.04, I've tried to fix the permission issue with carla, and checked that there's no current process on carla ports suggested by @PatrickPromitzer , did you solve this issue @SExpert12? Or is there any other suggestions?

The error message: Initializing new Carla server... Running simulation in single-GPU mode MESA: warning: Driver does not support the 0x7d67 PCI ID.

Thanks for your answer. I am extremely sorry for this late reply

@kicoi Hi, You need to try installation of packages again and again. This is because of package mismatch. Eventually you will get rid of this.

Best wishes
