Question

I am making some changes to our pipeline files in order to use the NugetCommand@2 task to restore nuget packages.
This is working fine on the Windows-Latest agent, but on the macos-latest agent (used for our iOS builds) this is failing.

      - task: NuGetCommand@2
        inputs:
          command: "restore"
          restoreSolution: "**/*.sln"
          feedsToUse: "config"
          nugetConfigPath: "nuget.config"  

Does anyone know why?

Our nuget.config file:

<?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <packageSources>
      <clear />
      <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
      <add key="ourserver" value="https://pkgs.dev.azure.com/ourserver/_packaging/ourserver/nuget/v3/index.json" />
      <add key="Skiasharp" value="https://aka.ms/skiasharp-eap/index.json" />
    </packageSources>
