your system may have some 'extra' source(s) like ppa(s) which disturb the installation. On my system (xenial 64) there is no problem for installing that package and all its dependencies. So clean your system (use gtkorphan to get rid of orphans), downgrade package(s) if necessary, be sure your have no conflicts with some other package(s)
