problem uninstalling ROS hydro [closed]

edit

Hi, I had a ROS electric installed on a Ubuntu 11.10 and yesterday I have decided to move to 12.04. I have decided to install also the latest version of ROS the hydro. I wanted to keep the electric version installed. I have tried with the installation once but it did not complete. After that I have tried to remove it using sudo apt-get remove ros-hydro-*, but it fails also this command because there are some dependency that depends on OpenCV in particular libplayerdrivers3.0.

What the hell is this package?

I do not understand if it is fully uninstalled or not and furthermore if I try to reinstall it I get the same error, Can anyone help me
