I'm trying to follow the instructions on this topic (http://www.howtoforge.com/how-to-upgrade-from-fedora-16-to-fedora-17-desktop-and-server) but I get the error below. It seems that the second mirrorlist path (below) has gone bad, since Fedora 17 has been end-of-lifed. What is the solution? How can I upgrade from 16 to 17? Please be specific in any instructions that you give (for example, "You should just install the XYZ tool" will be too vague).
