title: Git pull and push don't work
body: <p>I cloned an empty repository from a personal git server. After initial push (<code>push -u origin master</code>) I got some error but I pushed inside.</p>
  
  <p>Trying to use <code>git push</code> displays the following:</p>
  
  <blockquote>
    <p>No refs in common and none specified; doing nothing. Perhaps you
    should specify a branch such as 'master'. fatal: The remote end hung
    up unexpectedly error: failed to push some refs to
    'link-top-repository'</p>
  </blockquote>
  
  <p>Then I tried <code>git push origin master</code>:</p>
  
  <pre><code>Counting objects: 3, done.

  remote: error: refusing to update checked out branch: refs/heads/master
  remote: error: By default, updating the current branch in a non-bare repository
  remote: error: is denied, because it will make the index and work tree inconsistent
  remote: error: with what you pushed, and will require 'git reset --hard' to match
  remote: error: the work tree to HEAD.
  remote: error: 
  remote: error: You can set 'receive.denyCurrentBranch' configuration variable to
  remote: error: 'ignore' or 'warn' in the remote repository to allow pushing into
  remote: error: its current branch; however, this is not recommended unless you
  remote: error: arranged to update its work tree to match what you pushed in some
  remote: error: other way.
  remote: error: 
  remote: error: To squelch this message and still keep the default behaviour, set
  remote: error: 'receive.denyCurrentBranch' configuration variable to 'refuse'.
  </code></pre>
  
  <p>Problem starts when using <code>git pull</code>:</p>
  
  <blockquote>
    <p>Your configuration specifies to merge with the ref 'master' from the
    remote, but no such ref was fetched.</p>
  </blockquote>
  
  <p>I tried to check .git/config but it seems correct.</p>
  
  <pre><code>[core]
          repositoryformatversion = 0
          filemode = true
          bare = false
          logallrefupdates = true
          ignorecase = true
  [remote "origin"]
          fetch = +refs/heads/*:refs/remotes/origin/*
          url = junior@54blue.com:/repository/regulator
  [branch "master"]
          remote = origin
          merge = refs/heads/master
  [branc "master"]
          remote = origin
  </code></pre>
  
  <p>Any suggestions?</p>
