Flaky network / nuget downloads

[thomhurst]

Description

I've seen this for a couple of months now. Fairly often NuGet will error my pipelines with failures to download a package. Happens way too frequently nowadays so I assume something is wrong somewhere?

/Users/runner/.dotnet/sdk/8.0.401/NuGet.targets(174,5): error : The feed 'nuget.org [https://api.nuget.org/v3/index.json]' lists package 'Polly.8.4.1' but multiple attempts to download the nupkg have failed. The feed is either invalid or required packages were removed while the current operation was in progress. Verify the package exists on the feed and try again.

Hi @thomhurst ,

Thank you for bringing this issue to us. We are looking into this issue and will update you on this issue after investigating.

It being particularly problematic for the last couple of weeks might be related to NuGet/Home#13729.

@thomhurst Could you please confirm the platform on which you are facing an issue?

All OSs. So maybe @JonathanLydall is right with it being an SDK issue?

We've been seeing similar issues on macOS the last few days that Swift Package Manager tests that use binary dependencies are almost always failing with downloadError("The network connection was lost."). Examples at https://github.com/firebase/firebase-ios-sdk/actions/runs/10957246834/job/30424994614#step:5:102 and firebase/firebase-ios-sdk#13681 (comment)

Using the cache action is looking like a promising resolution to the binary Swift Package Manager network failures we were seeing. firebase/data-connect-ios-sdk#16

Sounds like they're workarounds that can help, but ultimately there's an issue that needs fixing

[RaviAkshintala]

Hi @thomhurst Could you please try with the below workaround.

[RaviAkshintala]

Hi @thomhurst Hope your issue resolves by using the below workaround.

      - name: Setup .NET
        uses: actions/setup-dotnet@v4
        with:
          dotnet-version: 8.0.401

Thanks, Closing this issue for now.
