I am pretty new to Linux, and our lab is using ROS, so I thought I would take the opportunity to learn about Linux and ROS by installing both on my home computer. Since I am starting from scratch, I am using Ubuntu 10.04 and cturtle, since those seem to be the latest of both. I then began to follow the instructions listed at http://www.ros.org/wiki/ROS/Installation/Ubuntu/Deb. This is what I got:

This seems like a huge amount of dependencies. Never the less... I started to work my way through them, but when I got to the circular dependencies of gcc-4.4 and libgcc-4.4, I had to stop. What am I doing wrong? My linux distro is simply named "ubuntu-10.04-desktop-i386.iso" and update manager says that it is up-to-date. Honostly, I am not sure where to look to see what build I have, or if that is even appropriate. Anyway, thanks for the help.
