mysql-workbench 6.1.7-1ubu1404 from the official mysql site is the the one that I had to change DEBIAN/control to replace "mysql-client" with "mysql-client-5.5 | mysql-client-5.6". It wouldn't install in my Ubuntu otherwise because it depends on mysql-client, which is removed when you uninstall mysql-client-5.5. After I rebuilt it and changed the dependencies, it installed fine.
