title: MSBuild NuGet.targets ,Nuget.exe : Unable to read package from path 'blah.nupkg' error
body: <p>I am getting these errors when running a MSBuild build step that builds a web project in TeamCity and I have setup my <strong>Nuget targets</strong> file PackageSource to point to a local Nuget server
  e.g. PackageSource Include="http://mylocaldevurl/nuget/Packages" .</p>
  
  <p>The build runs and produces errors of the form 
  e.g. Exec] F:\TeamCity\buildAgent\work\blahblah.nuget\NuGet.targets(87, 9): <strong>Unable to read package from path 'Lucene.Net.3.0.3.nupkg'.</strong></p>
  
  <p>Whats is strange other packages are downloaded fine to the TeamCity working folder -the <strong>package folder.</strong></p>
  
  <p>The local Nuget Server contains copies of my VS solution packages(the ones in the default packages folder) with only the .nupkg files.</p>
  
  <p>My question is there something that I need to do when copying the .nupkg files to that server.I might be missing something.</p>
  
  <p>I have already doubled checked that the packages exist in the local Server</p>
