Fedora 19 has reached its end of life for updates and support

As of 6th of January 2014, Fedora 19 has reached its end of life for
updates and support. No further updates, including security updates,
will be available for Fedora 19. A previous reminder was sent on
December 10th [0].

Fedora 20 will continue to receive updates until approximately one
month after the release of Fedora 22. The maintenance schedule of
Fedora releases is documented on the Fedora Project wiki [1]. The
Fedora Project wiki also contains instructions [2] on how to upgrade
from a previous release of Fedora to a version receiving updates.
