On the Ring official site, I clicked on "Join the Ring" button (which automatically takes me to the "GNU/Linux" option of the "Download" page), and I also selected "Ubuntu 14.04", but the instructions changed accordingly (from "Debian 8" to "Ubuntu 14.04"), I'm using Abrowser 47.0.
I'm currently viewing the information of the "ring" package I have, and the following dependencies seem to be non-existing (that is: they're not used/needed by the "ring" package I have): * libcamel * libcogl-pango20 * libcogl-path20 * libcogl20 * libqt5core5a (>= 5.3.0) (the package I have depends on >= 5.2.0) * libstdc++6 (>= 4.9) (the package I have depends on >= 4.8.1) As for "ring-daemon" package, make sure it's not being held, or broken.
