Hello all,

I've been following this tutorial in order to have 2 turtlebot robots working with nav2 amcl. So to reproduce that I only downloaded that workspace and launched:

ros2 launch turtlebot3_gazebo


ros2 launch localization_server

The problem is that when I try to launch the navigation to make them move to the pose published in rviz (apart from that tutorial)

ros2 launch nav2_bringup use_sim_time:=true namespace:="tb3_0"

I get this error:

[ERROR] [1680258456.257513729] []: Caught exception in callback for transition 10 [ERROR] [1680258456.257574221] []: Original error: Could not load library: cannot open shared object file: No such file or directory [WARN] [1680258456.257655084] []: Error occurred while doing error handling. [FATAL] [1680258456.257685068] [bt_navigator]: Lifecycle node bt_navigator does not have error state implemented
