Thank you for taking the time to report this bug and trying to help make Ubuntu better.
It looks like you had some PPA enabled before upgrade (you should always ppa-purge these before upgrading!) which has left incompatible packages on your system. Downgrading gnome-control-center to the version currently in Trusty (3.6.3) should resolve this issue ** Changed in: gnome-control-center (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1296974 Title: package gnome-control-center-shared-data (not installed) failed to install/upgrade: intentando sobreescribir `/usr/share/pixmaps/faces/leaf.jpg', que está también en el paquete gnome-control-center-data 1:3.8.6-0ubuntu1+unity8 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1296974/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
