Azure DevOps searches for nuget package in the wrong source

Question

I have a .NET solution which needs packages from 3 sources:

• Nuget.org
• My own organization
• Another feed

I have a nuget.config file with the following:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <clear />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="MyOrga" value="..." />
    <add key="TheOtherFeed" value="..." />
  </packageSources>
</configuration>

I have, in my projects, a reference to the package MyPackage which is in MyOrga, and to the package MyOtherPackage, which is in TheOtherFeed.

In my Azure DevOps pipeline, during the Nuget Restore task, it successfully finds the nuget.config and finds the 3 feeds. However, I get this error, which makes my task fail:

##[error]The nuget command failed with exit code(1) and error(NU1301: Failed to retrieve information about 'MyPackage' from remote source '<TheOtherFeed>/MyPackage/index.json'.

So it's basically only trying to get the package from the wrong feed, even though it found all 3 feeds (including the correct one). What did I do wrong?

Answer 1

You can get that error if your feed is not authenticated. Try adding a NuGetAuthenticate:

- task: NuGetAuthenticate@1

before you restore.
