Basically, As far as I know (please correct me if I am
wrong), TDE is
basically compiled for Debian/Ubuntu. Other people make it available for
other distributions, and usually only for the current release.
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
this choices:
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....)
