Repro Steps & Context

Our CI randomly fails during the dotnet restore phase, with errors like the following:

/usr/share/dotnet/sdk/8.0.401/NuGet.targets(174,5): error : The feed 'nuget.org [https://api.nuget.org/v3/index.json]' lists package 'Grpc.Tools.2.65.0' 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.

Other random examples:

/usr/share/dotnet/sdk/8.0.401/NuGet.targets(174,5): error : The feed 'nuget.org [https://api.nuget.org/v3/index.json]' lists package 'Grpc.AspNetCore.Server.Reflection.2.65.0' 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.

/usr/share/dotnet/sdk/8.0.401/NuGet.targets(174,5): error : The feed 'nuget.org [https://api.nuget.org/v3/index.json]' lists package 'Dapper.2.1.35' 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.

Each time, the package that's not found is a different one, so it seems totally random.

Of course, all these packages exists:

• Grpc.Tools.2.65.0
• Grpc.AspNetCore.Server.Reflection.2.65.0
• Dapper.2.1.35

Verbose Logs

No response

It seems completely random, and occurs with theses packages as well:

• Microsoft.NET.Test.Sdk
• Serilog.Formatting.Compact.1.1.0

Reruns are successful

Looks very much like: #13545.

This has been in the .NET 9 previews, maybe you can update to the latest .NET 9 previews to confirm whether you're still seeing issues?
