Fedora 30 EOL

Hello all,

As of the 26th of May 2020, Fedora 30 has reached its end of life for
updates and support. No further updates, including security updates,
will be available for Fedora 30. Fedora 31 will continue to receive
updates until approximately one month after the release of Fedora 33. 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.
