trinity nightly builds uninstallable in Debian Jessie

Hi there. I followed the instructions regarding nightly builds: $ cat /etc/apt/sources.list.d/trinity.list # Trinity nightly builds deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-build-de… jessie main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-build-de… jessie main deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-builds/d… jessie main deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-nightly-builds/d… jessie main After reloading I select desktop-base-trinity [OK] and tde-trinity [FAIL] Could not mark all packages for installation or upgrade The following packages have unresolvable dependencies. Make sure that all the required repositories are added and enabled in the preferences. tde-trinity: Depends: tde-core-trinity but it is not going to be installed Depends: tdeedu-trinity (>=4:14.0.0~) but it is not installable Depends: tdegames-trinity (>=4:14.0.0~) but it is not installable Depends: tdetoys-trinity but it is not going to be installed Depends: tdeaccessibility-trinity (>=4:14.0.0~) but it is not installable Depends: tdeaddons-trinity (>=4:14.0.0~) but it is not installable Depends: tdeadmin-trinity (>=4:14.0.0~) but it is not installable Depends: tdeartwork-trinity (>=4:14.0.0~) but it is not installable Depends: tdegraphics-trinity but it is not going to be installed Depends: tdemultimedia-trinity (>=4:14.0.0~) but it is not installable Depends: tdenetwork-trinity but it is not going to be installed Depends: tdepim-trinity (>=4:14.0.0~) but it is not installable Depends: tdeutils-trinity (>=4:14.0.0~) but it is not installable Depends: tdewebdev-trinity (>=4:14.0.0~) but it is not installable Any ideas?
