dotnet new --install Microsoft.AspNetCore.SpaTemplates::* fails when multiple packageSources are specified in NuGet.Config

Steps to reproduce

My NuGet.config looks like this:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="SomePrivateFeedKey" value="SomePrivatePackageFeed.json" />
  </packageSources>
  <disabledPackageSources>
    <add key="Microsoft and .NET" value="true" />
  </disabledPackageSources>
  <packageRestore>
    <add key="enabled" value="True" />
    <add key="automatic" value="True" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
</configuration>

Expected behavior

dotnet new --install Microsoft.AspNetCore.SpaTemplates:😗 // Should install, not give 401 error

Actual behavior

401 error seen. dotnet new --install Microsoft.AspNetCore.SpaTemplates:😗 Restoring packages for C:\Users\brruoff.templateengine\dotnetcli\v1.0.4\scratch\restore.csproj… C:\Program Files (x86)\dotnet\sdk\1.0.4\NuGet.targets(97,5): error : Unable to load the service index for source https://microsoft.pkgs.visualstudio.com/_packaging/EC.Platform/nuget/v3/index.json.\r [C:\Users\brruoff.templateengine\dotnetcli\v1.0.4\scratch\restore.csproj] C:\Program Files (x86)\dotnet\sdk\1.0.4\NuGet.targets(97,5): error : Response status code does not indicate success: 401 (Unauthorized).

#Workaround:

Removed 2nd entry

<add key="SomePrivateFeedKey" value="SomePrivatePackageFeed.json" />

from NuGet.config temporarily --> re-ran the command --> everything installed properly. --> Re-added the 2nd entry back to the NuGet.config.

I too am facing the same problem. I don’t understand why it wouldn’t try the next source? I even re-order them in VS to put nuget.org on top and it still failed.

This affected me too. The workaround unblocks me, but at the very least the guidance in the error message could be improved.
