Looks like / or /var (depending on your setup) is mounted read-only on your system. I believe that root is initally mounted as read-only and then remounted as read-write during boot, perhaps something is going wrong during the remount. Did you have a disk crash or something strange happen recently? Is the hard drive ok? You might want to try some of the utilities contained in the ultimate boot CD (http://www.ultimatebootcd.com) to check your disk for errors. In short, yum is failing because it cannot write its data to /var. If your / or /var partition is mounted read-only, I'd be surprised if this is the ONLY error you were seeing. Sincerely, Shawn M.
