Hi,
I have a Ubuntu 14.04 x64 server and I followed all your steps.
Since I have only one user on my server (I have disabled root login) and I already do an SSH login with that username, I ran the google-authenticator command logged in as user lupocatttivo@octane (lupocatttivo = username, octane = machine name):
lupocatttivo@octane:~$ google-authenticator

The only change I made is to the command: /etc/init.d/ssh restart
I used sudo service ssh restart instead as the above command did nothing (with or without "sudo" in front of it).

The procedure seemed to run smoothly, including the qr code generation etc. Then I rebooted the server and when asked to login I entered the username "lupocatttivo" and it logged in as usual without asking me any other code or pasword:

login as: lupocatttivo
Authenticating with public key "my-home-pc"
