Unable to update or install tdesvn-trinity

Hallo, since several week the Adept Notifier informs me that there are several updated packages: tdesvn-trinity and tdesvn-tdeio-plugins-trinity. But the neither the ubuntu-update-manager nor synaptic does the update. It remains in the state "should be updated". So i decided to try it with apt-get and run into a little problem. An update of tdnsvn-trinity isn't possible it needs tdesvn-tdeio-plugins-trinity An update of tdesvn-tdeio-plugins-trinity removes tdnsvn-trinity cause tdesvn-tdeio-plugins-trinity needs libsvnqt-trinity. And libsvnqt-trinity doesn't like tdnsvn-trinity. So it is impossible to update or install tdnsvn-trinity. My System is a Ubuntu-trusty-thar-box(14.04LTS) on a amd64-Core. Yours Werner
