I managed to clear that error by removing 'gnome-themes-standard', but the upgrade of the 'gnome-themes' package fails with this error:
gnome-themes: Depends: gtk3-engines-pixbuf but it is not installable A search for 'gtk3-engines-pixbuf' shows no such package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/734563 Title: [gnome3] Upgrading to Gnome3 PPA breaks Ubuntu theme defaults -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
