Straight dump of the traceback:

I'm confused: rospy is ROS 1, but you've tagged the question with ros2and the traceback mentions ROS Foxy .. (which is ROS 2).

And rospy is not supposed to be in /usr/lib/python3, but in /opt/ros.

Is this a mixed ROS 1 + ROS 2 install where the ROS 1 packages are actually UpstreamPackages?
