title: Unable to clone git repository from bitbucket in ubuntu
body: <p>I'm new to ubuntu, git and bitbucket.</p>
  
  <p>So, here is my problem: </p>
  
  <p>When I clone from bitbucket as https it gives me this error:</p>
  
  <blockquote>
    <p>fatal: unable to access '<a href="https://user@bitbucket.org/project/my_project.git/" rel="nofollow">https://user@bitbucket.org/project/my_project.git/</a>': Failed to connect to bitbucket.org port 443: Network is unreachable</p>
  </blockquote>
  
  <p>And if I clone from bitbucket as ssh it gives me this error:</p>
  
  <blockquote>
    <p>Cloning into 'my_project'...
    Permission denied (publickey).
    fatal: Could not read from remote repository.
    Please make sure you have the correct access rights
    and the repository exists.</p>
  </blockquote>
  
  <p>I have installed Git on my Ubuntu 14.04
  Did I miss something? I don't understand.</p>
