The dotnet-source-build-lite pipeline is failing with the following error:

Example build (internal link)

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

This is also failing in Unified Build: example (internal link). It doesn't seem to be associated with a code change but rather a feed or network change?

pinging @jeffkl, @nkolev92 for any insight

Hard to tell on a first look.

Seems like the source wasn't accessible.

Did the SDK version change recently?

Just as a test, can you run dotnet add package DoesNotExist to some project? It will show inner exceptions, and therefore explain why the service index can't be loaded.

However, I don't see the Azure Pipelines NuGetAuthenticate task being run, so I suspect that it isn't sending credentials to the private feed. If this worked before, I don't know how or why. My understanding is that it's always been necessary to set up the credentials in Azure Pipelines before trying to access the private feed.

It looks like this was a transient error. Builds are passing now.

Reopening as the latest builds failed again due to the same issue. Now, it is affecting the 9.0 and 8.0 repos.
