How to upgrade Mopify to the latest version without breaking everything?


I’m trying the Pi MusicBox to listen my music from my Spotify account.
The web interface of MusicBox is great but Mopify seems more usable for me.

But unfortunately, the latest Pi MusicBox comes with the version 1.1.2 of Mopify wich is a old version (current version is 1.5.16).

When I try to update to the latest version using the command sudo pip install --upgrade Mopidy-Mopify described in GitHub page of Mopify, I cannot access to any webclient.

Do you know how can I upgrade it safely?

Thank you!
