Local and Authenticated NuGet source break Package Restore

[wldevries]

The machine learning notebooks reference Microsoft.ML version 2.0.0-preview.22356.1 from a private Azure DevOps server. This preview version of the Microsoft.ML package is not available from nuget.org making it hard to run the notebooks.

PackageManagement Error 3217 Invalid URI: The format of the URI could not be determined.

@wldevries they’re all public feeds. It is azure dev ops but it’s a public feed of our daily builds.

Can you share a screenshot of what you’re seeing?

sharing the notebook would be helpful too!

[wldevries]

This is what I'm seeing. Note that I'm using Notebook Editor in Visual Studio Pro 2022.

That's so strange ..

What happens when you visit https://pkgs.dev.azure.com/dnceng/public/_packaging/MachineLearning/nuget/v3/index.json in your browser?

[JakeRadMSFT]

@michaelgsharp is there any reason why this feed might be having issues?

[wldevries]

That url returns a json, but most of the links in there return "The resource cannot be found."

[JakeRadMSFT]

@wldevries - can you check your NuGet configs to see what other feeds are in there?

They're usually at these locations:

%appdata%\NuGet\NuGet.Config
%ProgramFiles(x86)%\NuGet\Config

[wldevries]

I have some local directories, a local server and the following official source declared:

<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />

[JakeRadMSFT]

Can you try removing any local directories and servers temporarily?

I think this is a bug on our end but I want to try to understand what the problem is.

[wldevries]

It seems having the local server in the nuget config caused the problem. Removing that and leaving the local sources in made it work.

I also had this official source in, not sure what it does. It did not cause the issue though.

    <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\" />

[JakeRadMSFT]

Thanks for trying that out and reporting back! I'll see if we can catch that better and give a better error message.

[JakeRadMSFT]

@wldevries - are there any special characters in the path that didn't work?

It might be related to: dotnet/fsharp#12401

[TechInceptions]

It's not only local Nuget that is the problem:

My Azure Dev-Ops hosted nuget feed throws a 401.

Had to uncheck it and restart VS 2022 before I could run the 1st couple of steps in the notebook
