title: Repository Not Found when pushing to GitHub remote
body: <p>I created a repository on GitHub called 'messages' and a local repository with the same name. I am trying to push the files from my local repo to the remote but get this error:</p>
  
  <blockquote>
    <p>ERROR: Repository not found.<br>
    fatal: The remote end hung up unexpectedly.</p>
  </blockquote>
  
  <p>I figured it was an authentication issue. And when I ran </p>
  
  <pre><code>ssh -T git@github.com
  </code></pre>
  
  <p>I did get a message indicating that my key did not work. So I added my ~/.ssh/github_rsa.pub to the SSH keys in my account on GitHub (deleted the one that already existed there) and ran the command again. This time I received a message saying -</p>
  
  <blockquote>
    <p>Hi septerr! You've successfully authenticated, but GitHub does not provide shell access.</p>
  </blockquote>
  
  <p>From what I read this seemed to be the expected message. So, I again tried the push. But received same error. Repository not found.</p>
  
  <pre><code>Swapnas-MacBook-Pro:messages sony$ git remote -v show
  origin  git@github.com:seterr/messages.git (fetch)
  origin  git@github.com:seterr/messages.git (push)
  Swapnas-MacBook-Pro:messages sony$ git push -u origin master
  ERROR: Repository not found.
  fatal: The remote end hung up unexpectedly
  </code></pre>
  
  <p>When I look at my repo on GitHub I see: </p>
  
  <blockquote>
    <p>Existing Git Repo?<br>
    <code>cd existing_git_repo</code><br>
    <code>git remote add origin git@github.com:septerr/messages.git</code><br>
    <code>git push -u origin master</code></p>
  </blockquote>
  
  <p>What could be wrong?</p>
