Tienes que aceptar las dependencias y esperar un buen rato hasta que se instale todo.
Tienes que tenerlo así:
Código:
# kde.repo, v2.1
[kde]
name=kde
mirrorlist=http://apt.kde-redhat.org/apt/kde-redhat/fedora/mirrors-stable
gpgkey=http://apt.kde-redhat.org/apt/kde-redhat/kde-redhat.RPM-GPG-KEY
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-kde-redhat
skip_if_unavailable=1
enabled=1
[kde-testing]
name=kde-testing
mirrorlist=http://apt.kde-redhat.org/apt/kde-redhat/fedora/mirrors-testing
gpgkey=http://apt.kde-redhat.org/apt/kde-redhat/kde-redhat.RPM-GPG-KEY
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-kde-redhat
