Last night when fedora 10 came on air, it was a painful sleep at home, because i was unable to manage myself without upgrading my office's desktop PC to fedora 10, of course the best way that suites me is using yum, so here are those two steps that accomplished my objective today:
#rpm -Uvh your-mirror/fedora/releases/10/Fedora/i386/os/Packages/fedora-release-10-1.noarch.rpm your-mirror/fedora/releases/10/Fedora/i386/os/Packages/fedora-release-notes-10.0.0-1.noarch.rpm
#rpm -Uvh http://ftp.univie.ac.at/systems/linux/fedora/releases/10/Fedora/i386/os/Packages/fedora-release-10-1.noarch.rpm http://ftp.univie.ac.at/systems/linux/fedora/releases/10/Fedora/i386/os/Packages/fedora-release-notes-10.0.0-1.noarch.rpm
#yum clean all
#yum update -y
PS: You need to run all above commands as root !
