I just did a test run: sudo torify apt-get install wayland qt5* and I find that I already have xwayland and several other wayland deps installed, as well as all kinds of qt5 packages; in fact, there are more installed than are not. It is simpler and much shorter to give the error output: ************ Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: autokey-qt : Depends: python-kde4 but it is not going to be installed freeciv-client-qt : Depends: freeciv-data (= 2.5.6-1~bpo8+1) but 2.4.3-3 is to be installed Recommends: freeciv-server (= 2.5.6-1~bpo8+1) but it is not going to be installed golang-github-jacobsa-reqtrace-dev : Depends: golang-go.net-dev (>= 0.0+git20150226.3d87fd6) lcl-qt4-1.6 : Depends: lcl-gtk2-1.6 but it is not going to be installed Depends: lcl-nogui-1.6 but it is not going to be installed libclam-qtmonitors-dev : Depends: libclam-dev but it is not going to be installed libgwengui-qt4-dev : Depends: libgwenhywfar-core-dev (= 4.15.3-5~bpo8+1) but it is not going to be installed Depends: libgwengui-qt4-0 (= 4.15.3-5~bpo8+1) but 4.12.0beta-3+b1 is to be installed libgwengui-qt5-dev : Depends: libgwenhywfar-core-dev (= 4.15.3-5~bpo8+1) but it is not going to be installed libqt4-phonon : Conflicts: libphonon4 but 4:4.8.0-4 is to be installed marble-qt : Depends: libmarblewidget19 (= 4:4.14.2-1) but it is not going to be installed phonon4qt5-backend-null : Conflicts: phonon4qt5-backend qt-sdk : Depends: libphonon-dev but it is not going to be installed qt4-default : Conflicts: qt5-default but 5.3.2+dfsg-4+deb8u2 is to be installed qt5-default : Conflicts: qt4-default but 4:4.8.6+git64-g5dc8b2b+dfsg-3+deb8u1 is to be installed E: Unable to correct problems, you have held broken packages. ************ I don't see the ProtonMail bridge listed here (but maybe I don't recognize the name); but overall it seems that most qt5 packages work just fine with TDE, at least on my system, which is Debian Jessie 8.x (whatever the latest updates). What are the packages that you want to install? I'll give them a try. Bill
