Problem re-installing ROS
I have removed ROS in order to solve some problems I had, but I removed the "ros" folder in /opt sending it to the trash, which I think was a bad idea.
I have tried to reinstall ROS again, but when I do $ sudo apt-get install ros-electric-desktop-full
only the "stacks" folder is created inside /opt/electric.
I have done $ sudo apt-get remove ros-electric-desktop-full and tried to reinstall it again, but i doesn't work.
What should I do to get ROS again, please?
Thank you
