Harry, we allow both libs on the ppa builds to be co-installable, but the archive builds require a full transition anyway (all reverse deps get rebuilt). Also the debian guys claim there are issues having them co-installable, from the changelog
[ Andreas Henriksson ] * libgnome-desktop-3-12: Add Breaks: libgnome-desktop-3-10 - Forces a full upgrade. This is to prevent applications linking to and using both at the same time (which leads to crashed). That happens in eg. gdm3 built against libgnome-desktop-3-10 when using gir1.2-gnomedesktop-3.0 3.18.0-1 (built against libgnome-desktop-3-12). (Closes: #801603) Anyway the real solution to your problem is to disable xenial-proposed on your system, its not meant for human consumption. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1510813 Title: Update to 3.18.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop3/+bug/1510813/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
