TFS 15 RC2 - Build Agent Publish to Packages Feed
<p>I've been unsuccessful with having my build publish to the new Package Feed in TFS 15 RC2.  I'm currently running TFS offline and using a local build agent.  I've followed these <a href="https://www.visualstudio.com/en-us/docs/package/build/team-build" rel="nofollow">instructions</a> to no avail.</p>

<p>Since the last image in those instructions is cropped around the URL, and that URL was specific to VSTS online, I thought mine might be wrong.  So I tried the following (none worked):  </p>

<ol>
<li>Using <a href="http://[computername]:8080/tfs/DefaultCollection/_packaging/" rel="nofollow">http://[computername]:8080/tfs/DefaultCollection/_packaging/</a>{feedName}/nuget/v3/index.json
gives an error when it tries to prompt for input of credentials in
interactive mode.   </li>
<li>Using <a href="http://[computername]:8080" rel="nofollow">http://[computername]:8080</a> gives a 404.</li>
<li>Using <a href="http://[computername]:8080/tfs" rel="nofollow">http://[computername]:8080/tfs</a> gives same error as #1.</li>
<li>Using <a href="http://[computername]:8080/tfs/DefaultCollection" rel="nofollow">http://[computername]:8080/tfs/DefaultCollection</a> gives same error as #1</li>
</ol>

<p>Since some errors happened while trying to do an interactive prompt, I thought it might be a permission error.  The following links give some information, but it seems like the Build Agent should already be in the right category for publishing permissions.</p>

<ul>
<li><a href="https://www.visualstudio.com/en-us/docs/package/feeds/common-identities" rel="nofollow">https://www.visualstudio.com/en-us/docs/package/feeds/common-identities</a></li>
<li><a href="https://www.visualstudio.com/en-us/docs/package/nuget/auth" rel="nofollow">https://www.visualstudio.com/en-us/docs/package/nuget/auth</a></li>
</ul>

<p>Anyone happen to know a solution?  Thanks!</p>

<h2><strong>EDIT</strong></h2>

<p>The build agent was running as NT AUTHORITY/Network Service, which is the default of the agent config.  I removed this agent and configured it to run under my user account, which is an admin on the system.  After doing so, I was able to publish without issues to the Packages using the URL in #1 (as Cece below has written).  Is there something else I need to do to get the permissions set for the default agent?</p>
