title: Unable to push to repository using GIT Extensions
body: <p>I'm pulling my hair out right now because of this. I have downloaded and installed GIT, did the same for GIT Extensions (as we're going to be using it for VS2010), and everything worked fine and dandy. I committed changes, then found out my team members couldn't checkout from the website. Appears that I have to push my changes to the server. </p>
  
  <p>So here's the deal. When I try to push to the github.com website, I get the following error message:</p>
  
  <p>"Authentication error
  The command resulted with an error that usually means that th
  PuTTy authenticaion agent is not running.or that the correct
  private key is not (yet) loaded.</p>
  
  <p>When the key is loaded, you can press retry.
  'Retry' 'Load SSH key' 'Abort'"</p>
  
  <p>I have created an SSH key, so I try to load it. I get to browse for my key, which I do. I press 'Load', then 'Retry'. Then, the same error appears.</p>
  
  <p>OK, so that doesn't work. I go to FileMenu Remotes -> PuTTY -> Start Authentication Agent. I get an error that it is already running, so that should be fine then. Going to Remotes -> PuTTY -> Generate or import key, shows me that it doesn't have a key loaded or anything, but I assume that that's fine as well then.</p>
  
  <p>Remotes -> Manage remote repositories. I get to see the URL of my repo, and the location of my .ssh key. Pressing 'Test Connection' will give me the following error: </p>
  
  <p>"Using username 'git'
  FATAL ERROR: Disconnected: No supported authentication methods available"</p>
  
  <p>So here I am, I can't push to the server because of above issues. I always solve problems on my own or find solutions on Google, but I'm left in the dark here, it just won't work. Anything that would help me get out of this Source Code Management disaster would be awesome, because I could just about kill anyone now.</p>
  
  <p>Thanks!</p>
  
  <p>Edit: I should note that the problems started when the push told me something like 'Unable to verify the server is actually the server, because I dont know the key of the server'. I then tried to troubleshoot that, which resulted in the above. Maybe that helps..</p>
