Hi,  
I am using the Ros2 real robot ROSJECT.

Everything was well but suddenly I am not able to start ros1\_bridge. I am getting the following errors

user:~/ros2\_ws$ source .bashrc\_ros2  
not found: “/home/user/ros2\_ws/install/turtlebot3\_node/share/turtlebot3\_node/local\_setup.bash”

user:~/ros2\_ws$ ros2 run ros1\_bridge dynamic\_bridge  
/home/simulations/ros2\_sims\_ws/install/ros1\_bridge/lib/ros1\_bridge/dynamic\_bridge: error while loading shared libraries: librosconsole.so: cannot open shared object file: No such file or directory

Hi,

Like it shows in the course, in the terminal that you are launching the bridge you must source ROS noetic first, and then ROS foxy:

> source /opt/ros/noetic/setup.bash  
> source /opt/ros/foxy/setup.bash

Then, you can run the bridge. I will update the notebook to specify the sourcing.
