Comment 27 for bug 1596648

@Bill: Unless you are running the development branch of Elementary (using the daily repository : deb http://ppa.launchpad.net/elementary-os/daily/ubuntu/ xenial main) you will need to install the testing branch in order to replace the plugin modules. Otherwise, like Fabrice, the testing branch may not run locally. So while in your build directory in a terminal, after building, type "sudo make install". After that you can run the testing branch locally in the terminal, while in the build directory and after stopping any Files processes that might be running in the background, by typing "./src/pantheon-files --debug" and it will output various messages while it tries to connect to your server.
