title: Git master branch has no upstream branch
body: <p>I'm trying to push one of my projects to github, and I keep getting this error:</p>
  
  <pre><code>fatal: The current branch master has no upstream branch.
  </code></pre>
  
  <p>I've never seen this before. I re-initialized my git, re-added my origin, deleted and re-made the repo, and recreated my SSH key.</p>
