  <p><code>fatal: The remote end hung up unexpectedly</code></p>
  
  <p>What tests can I run to figure out what's going on?  I've created a brand new git repository, and it won't push!</p>
  
  <p>Here are some of the standard diagnostics suggested by other StackOverflow questions:</p>
  
  <pre><code>$ ssh -T git@github.com
  Hi keflavich! You've successfully authenticated, but GitHub does not provide shell access.
  </code></pre>
  
  <p>I'm set up to use ssh:</p>
  
  <pre><code>$ git remote -v
  origin  git@github.com:keflavich/turbulence_pdfs.git (fetch)
  origin  git@github.com:keflavich/turbulence_pdfs.git (push)
  </code></pre>
  
  <p>I get warnings about X11 auth:</p>
  
  <pre><code>$ git push -vu origin master
  Pushing to git@github.com:keflavich/turbulence_pdfs.git
  Warning: untrusted X11 forwarding setup failed: xauth key data not generated
  Warning: No xauth data; using fake authentication data for X11 forwarding.
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>but these shouldn't matter.</p>
  
  <p>EDIT: https doesn't work either... maybe this is just a github service outage?</p>
