Mobile travel sample app does'nt build - CBL packages nugets


I cloned .NET/Xamarin.Form version of the mobile travel sample, accessible here :

It doesn’t build on my Mac (Visual Studio for Mac) because of a problem finding CBL Nuget packages. I get the following error Message :
Unable to find package Couchbase.Lite.Support.Android. No packages exist with this id in source(s):

I tried to restore the packages but got the same error.


Please add the Couchbase nuget feed to your sources (as described here)

How to do this concretly?
here is the contains of my Nuget.config file :

 ?xml version="1.0" encoding="utf-8"? 
     add key="" value="" protocolVersion="3" / 

ps : I removed the < and > cause it make the code block does’nt appear

The easiest way to do it is this:

EDIT Just remembered you are using Mac, but the process is similar

It works thank you. I get some warnings but its common warnings, I can get the app running.
