Before my last log off I started to look at the UDRF tutorial. I’m not sure if that may have caused this glitch.
I was working on lessons in ROS for Beginners 5 days course and I logged in today and found that all my stuff in catkin_ws/src was deleted. I did not deleted them.
After looking around a bit I tried to redo the examples and I found that ros is not available to me. When I tried to roslaunch the examples it did not work.
As you can see ros is not initiated in the shell. If I switch to the UDRF 8 hour course ros is re-initiated and when I run the UDRF examples with roslaunch it works. So I am wondering if this can be fixed because I want to finish the Ros Basics course. Also is there a way to restore my files back or do I have to make new files.
