After trying to add the repositories for 16.10 it doesn't even show up in the sources. After running terminal for the upgrade it stated: 

org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.87'}): org.debian.apt.update-cache

You need to type sudo apt-get dist-upgrade it will ask you for your password then you can proceed to the upgrade. Make sure you have the repositories for 17.04 Zesty so you can upgrade.
