Ok, I got to the bottom of it. I'm assuming you are having the same problem I was having initially. In order to install ROS, you need to enable the additional repository components: "restricted," "universe," and "multiverse." You can find out more about how to do this on the ubuntu help site: https://help.ubuntu.com/community/Repositories/Ubuntu Once you enable those 3 additional components, the debs should install just fine.
