I am working through the ROS2 for Python course when I ran into an issue with the course in Unit 4 and in attempting to fix it messes up a few of the other files beyond repair. Is there a way to reset my progress back to the beginning of Unit 4 without wiping back to the start of the source? If not how do I go about doing this because this is the only way forward I can see.
Hi @Perhaps0108, welcome to the community!
Yes, you can simply delete the files you created for Unit 4.
To make your workspace isn’t using old precompiled files, you can delete your workspace compilation folders, compile, and source your workspace:
cd ~/ros2_ws
rm -rf build/ install/
colcon build && source install/setup.bash
