Additional info:
I just upgraded from fc17 to fc18. This is the first software update being performed I believe. There was previously another error with yum update I didn't capture which happens even before yum try to download any update package. Then I ran the command "yum --nogpgcheck install http://rpm.livna.org/livna-release.rpm http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm". 

After that, yum update got further ahead by downloading all the update packages but then failed on transaction check.
