TDE is mostly developed in Debian/Ubuntu (me, Tim, Slavek) and Francois takes on all the huge effort to maintain
rpm-based builts for several distros (RHEL/CentOs, Opensuse, Fedora). For each distro the last few versions (2 or 3
usually) are supported, but for matters of time, server space, bandwidth, etc... older distros are progressively dropped
as new versions are added. Debian/Ubuntu supports a few more, but basically only because the building process is
completely automated and reuse the files that are already maintained for the latest versions.
in addition to this, there are some other builds made by "external" contributors (Debian, Slakware, PCLinux and Q4OS).
So in brief, I am afraid but TDE does not support Fedora 20 any more. If you want to use TDE in Fedora, you have one of
1) upgrade to a more recent Fedora version
2) download the source file and build TDE in Fedora 20 yourself (probably the building scripts for Fedora 21 may still
be used, I guess....)
