So, I have a brand new Debian install.  My sources.list looks like this:deb http://http.debian.net/debian wheezy main contrib nonfreedeb-src http://http.debian.net/debian wheezy main contrib nonfreedeb http://http.debian.net/debian wheezy-updates main contrib nonfreedeb-src http://http.debian.net/debian wheezy-updates main contrib nonfreedeb http://security.debian.org/ wheezy/updates main contrib nonfreedeb-src http://security.debian.org/ wheezy/updates main contrib nonfreeHowever, I can't so much as install vim - it tells me no installation candidate found!I started by trying to install the nvidia drivers as provided here.  However, I keep getting errors in both aptitude and apt-get, that a dependency package cannot be installed, and when I try to do it manually - no installation candidate..  I fixed one of these errors by downloading packages manually as a proof of concept.And yes, I ran apt-get update.  Could someone be so kind as to tell me how to fix my package manager?
