I'm in a situation where I need to install openni-dev on Ubuntu with a pre-existing and working installation of Hydro. The problem is that when I run sudo apt-get install openni-dev, I get this message saying that it will be removing a lot of my ROS packages. I accepted once and my ROS install was completely broken. Is there any way to get around this weird behaviour?

  The following packages were automatically installed and are no longer required:
