Fedora 22 has reached it's end of life for updates and support

As of the 19th of July 2016, Fedora 22 has reached its end of life for
updates and support. No further updates, including security updates,
will be available for Fedora 22. A previous reminder was sent on 22nd
of June [0]. Fedora 23 will continue to receive updates until
approximately one month after the release of Fedora 25. 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.
