title: Error "NU3034 This package is signed but not by a trusted signer"
body: <p>Today I found myself unable to restore NuGet packages on my machine. Doing so produces errors resembling:</p>
  
  <blockquote>
    <p>Myproject.csproj : error NU3034: Package 'SomePackage 1.2.3' from source '<a href="https://api.nuget.org/v3/index.json" rel="noreferrer">https://api.nuget.org/v3/index.json</a>': This package is signed but not by a trusted signer.</p>
