That "howto" proposes to add a PPA that probably contains non-free software.  
That is why I instead suggested to only download the necessary .deb from it  
(Go-mtpfs is free software).

However, I believe the PPA Abhishek found is a better source. It only  
proposes the necessary software as developed by the GNOME project.
