I'm new on Ubuntu and ROS. I installed two different distro. (groovy and hydro). When I open the terminal I take this error.
bash: /opt/ros/groovy/setup.bash: No such file or directory
I remove ROS. I search on internet, type
gedit ~/bashrc to delete
/opt/ros/hydro/setup.bash in it.
But this file is empty in my case. How can I get rid of this error?
