I am trying to follow the nav2 basic tutorial from Nav2 - Getting started.
ros2 launch nav2_bringup tb3_simulation_launch.py headless:=False
- ROS Distro = humble
- Python version = 3.10
- Ubuntu = 22.04
I am getting following error repetitively. Not sure what am I missing here.
I tried reinstall, restarts, use python virtual environment, export gazebo model path etc. Nothing worked so far. Any hints on how to debug this ?
