Hello,
I would like to have a freshly reset environment for the course. I broke my packages and can now no action are displayed when using “ros2 action list” in my terminal.
I saw in a post from september 11 2025 that you can reset them.
Could you please help me reset mine?
Regards,
Just delete the whole ros2_ws and then change to another course. Once you come back to the wrong course, a fully new environment would have been regenerated.
Remember to make a copy into a git or your local machine of your files if you want to preserve them, so once the environment is regenerated, you can be copying file by file until you find the point where you messed it up
