Hi,

For some time there is this build warning (882 times in the build) for each nuget package

> WARNING: NU3005: Package 'System.ValueTuple 4.5.0' from source 'C:\Program Files\dotnet\sdk\NuGetFallbackFolder': The package signature file entry is invalid. The central directory header field 'compression method' has an invalid value (8).

Everything works, but it pollutes the build log. What could we do to get rid of this warning?

    Can you send a link to the build? I tried to manually download System.ValueTuple 4.5.0 and run NuGet.exe verify -signatures "C:\Users\appveyor\Downloads\system.valuetuple.4.5.0.nupkg" in RDP session to the build worker, and it executed OK on both Visual Studio 2017 and Visual Studio 2015 images...
