title: specifying git branch for remote
body: <p>I'm trying to update my webbynode pulling from github but I got the message below:</p>
  
  <blockquote>
    <p>You asked to pull from the remote 'git@github.com:sigbackup/gsapp.git', but did not specify
    a branch. Because this is not the default configured remote for your current branch, you must specify a branch on the command line.</p>
  </blockquote>
  
  <p>So I have checked out this forum for help and I found some comments regarding <code>.git/config</code> file but mine looks already fine (at least to me):</p>
  
  <pre><code>[core]
          repositoryformatversion = 0
          filemode = true
          bare = false
          logallrefupdates = true
  [remote "origin"]
          fetch = +refs/heads/*:refs/remotes/origin/*
          url = git@github.com:sigbackup/gsapp.git
  [branch "master"]
          remote = origin
          merge = refs/heads/master
  [branch "origin"]
          remote = origin
          merge = refs/heads/master
  </code></pre>
  
  <p>Am I missing something?
  Any ideas how I can solve it?</p>
  
  <p>PS I also tried <code>git pull origin git@github.com:sigbackup/gsapp.git</code> and I got</p>
  
  <blockquote>
    <p>fatal: Couldn't find remote ref git@github.com</p>
