Can't resolve packages

[wjk]

OK... After resolving the issue regarding spaces in the path that was causing dotnet-cli to crash immediately on launch, I now ran into another issue. When I run dotnet restore, it fails to resolve any of the NuGet packages specified in my project.json. Here's the console output when I try:

Can anyone help me? @wtgodbe is waiting for my input to triage coreclr#2143, and I cannot provide him any feedback due to this issue. He has asked twice now, and I do not want to keep him waiting much longer.

(On an aside: Not to be mean, but whose idea was this large, breaking change, anyway? .NET CLI used to just work for me, but now I cannot even restore packages successfully. This is really annoying because I cannot continue working on my .NET Core app until these issues are resolved!)

what feeds are you using ? what does your nuget.config look like ?

AFAIK, only the official (nuget.org) one. I don't have a nuget.config file in my solution, either.

create a NuGet.Config at the root of your project and add this to it.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <!--To inherit the global NuGet package sources remove the <clear/> line be$
    <clear />
    <add key="dotnet-core" value="https://www.myget.org/F/dotnet-core/api/v3/index.json"/>
    <add key="api.nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

If you are non-windows the name of NuGet.Config should be as is. Another way is to create a new project using "dotnet new" and copy the nuget.config to your project.

Thanks! That did it! The packages are now restoring. Just FYI, the code block your above post is garbled; the lines ending with $ have been truncated. Thanks so much!
