带有 Azure DevOps Artifacts feed 的 NuGet 上游源的安装包失败

Question

Problem

I'm attempting to install a package from a public repository. I want to use the PackageSource External . This is a Azure DevOps Artifacts Feed that is configured with NuGet Gallery as an Upstream source . Since NuGet Gallery is an upstream source, my request for a package should pass through Artifacts and be fulfilled by the Upstream source, but instead it errors and says that there's no match.

On the other hand, if I submit the same request using a PackageSource that is pointing directly to NuGet Gallery, it works. Could the Upstream source functionality in Artifacts be broken?

The Upstream source feature works well in my side. However, I didn't get this promote info during install package.

This seems related to your local security setting. Have no idea how to enable or disable. However, according to your description and situation. In my opinion, I was wondering if there is a jump during your installing package with Azure DevOps Artifacts package source.

Since unlike directly connect NuGet Gallery, you need first access Azure DevOps Artifacts Feed first, then through upstream source to fetch that package. You could not select the trust info, it choose default (default is "No"). Finally, you could not install that package.

You could turn off your local security setting and try it again, which may do trick. If due to policy, you could not turn it off.

As a workaround, you could create a need feed with upstream off and upload your package in feed as package source.

Answer 2

So after doing some additional testing, I did discover that using the nuget.exe CLI worked where the Install-Command cmdlet was failing me.

I'm unfortunately still not entirely sure why this behavior is happening.

Below is my version of Install-Package

>Get-Command -name 'Install-Package'

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Cmdlet          Install-Package                                    1.4.3      PackageManagement

And also my version of nuget.exe

>nuget
NuGet Version: 5.2.0.6090

Finally, here's output from the nuget.exe command succeeding.
