As of the 12th of December 2017, Fedora 25 has reached its end of life
for updates and support. No further updates, including security
updates, will be available for Fedora 25. Fedora 26 will continue to receive
updates until approximately one month after the release of Fedora 28.
The maintenance schedule of Fedora releases is documented on the
Fedora Project wiki [0]. The Fedora Project wiki also contains
instructions [1] on how to upgrade from a previous release of Fedora
to a version receiving updates.
