Fedora 19 is winding up to release soon, and so it's that time in the cycle when a new fedora-release package pushes out that disables the fedora-updates-testing repository so folks who install after this point don't get testing packages unless they opt in. That update just pushed into the base Fedora 19 repo today: https://admin.fedoraproject.org/updates/fedora-release-19-2 This means if you have a Fedora 19 install you installed before today you very likely have updates-testing packages installed. You should do one of the following things: a) If you wish to help test updates ( https://fedoraproject.org/wiki/QA:Updates_Testing ) You should simply re-enable the updates-testing repoistory: "sudo yum-config-manager --enable updates-testing" and go on to help test and provide feedback for testing updates. b) If you do not wish to continue to test updates-testing packages, you will need to sync your install with only the released/base/stable repository: "sudo yum distro-sync" and then you can move forward only getting the normal updates. Note that in both cases you should continue to have the base fedora repository and the fedora-updates repository enabled. See 'yum repolist' if you wish to see what you have enabled.
