Repro Steps & Context

An error bearing an incorrect message occurs during a NuGet Restore action when the current user is not authenticated to the referenced feed.

For example:

NU1301: Unable to load the service index for source {source}

This error occurs during an Azure DevOps pipeline build when the project-scoped build identity {Project Name} Build Service ({Org Name}) is omitted from the referenced feed's permissions (assuming an Azure DevOps feed).

The fix for this is easy—simply add the project-scoped build identity to the feed's permissions.

Unfortunately, however, the error message is misleading. It doesn't describe the root problem, leaving developers and DevOps engineers in the dark as to how to address it. The abundance of reports and attempted/failed solutions found at StackOverflow and elsewhere attest to this.

To reproduce:

1. In Azure DevOps (Services or Server), create a new collection-scoped feed
2. Note that the feed's permissions do not include the project-scoped build identity
3. Publish a package to the feed
4. Create a Git repository
5. Create a pipeline build that consumes the repository and is triggered by a git push
6. Add a nuget restore step to the pipeline
7. In the nuget restore step, reference the feed
8. Create a Visual Studio project that references the package
9. git push the code to the repository
10. Note the misleading error message in the build's logs
11. Add the project-scoped build identity to the feed's permissions
12. Run the pipeline again (afresh, not a rerun)
13. Note that the error no longer occurs

The message can be adjusted to more accurately reflect the error it attempts to describe.
