I think we resolved this issue. We had this problem every day in some boxes after update from precise to trusty. When we tried to update wine, we can't because synaptic found broken packages. The history was that solving wine problem we solved this too. A fast search for packages versions with "precise" text in there give us as result some libs, etc. Removing them and updating them solved our problem.
