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 Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/1510813 Title: Update to 3.18.1 Status in gnome-desktop3 package in Ubuntu: Fix Committed Bug description: Please merge 3.18.1 from debian Debdiff attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop3/+bug/1510813/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
