I have no idea what prompted me to do this, but I decided to upgrade my current Fedora Core 6 install to a Fedora 7 install on my Dell D620. I followed the link http://fedoraproject.org/wiki/YumUpgradeFaq to upgrade from FC6 to Fedora 7.
Upgrade to Fedora 7
Although FEDORA STRONGLY RECOMMENDS YOU DO NOT DO THIS, I did it anyway. There was a simple .rpm file install and then issuing the command
I started the whole process. I began with about 700 packages to update/upgrade/install. After having several dependency issues, uninstalling mplayer and something else, I realized that I was having an inordinate number of mirror errors. So I disabled the development repo and issued the same yum command. This time I upgraded about 1300 packages and installed about 700 new packages. This took quite some time. I was ridiculous about somethings though. Why didn’t I back up some of my stuff? Good question.
I had to unisntall the cpp, libgomp, adn libgcf-devel pacakges regardless of dependencies so I could isntall the gcc-4.1.2-12 package manually. I was then able to install the necessary ipw3945 pacakges for wireless network connectivity. I then reinstalled those packages using the yum package manager.
