Hi, According to the wiki, it's simply not possible to upgrade to F12 from F10 or lower directly, see: http://fedoraproject.org/wiki/YumUpgradeFaq#Fedora_11_-.3E_Fedora_12 It says: It is not possible to update directly from Fedora 10 or earlier with yum. To upgrade from Fedora 10, first update to Fedora 11, and then upgrade from Fedora 11 to Fedora 12. If you are using a release before Fedora 10, use one of the official upgrade methods or backup your data, perform a fresh installation, and restore from backup. Good luck! > On Mon, 2010-03-29 at 08:36 -0400, Kevin J. Cummings wrote: >> I was only able to use "preupgrade" to go from F9 to F11. For >> whatever >> reason, F9 to F12 did not work for me.
