title: GnuTLS recv error (-110): The TLS connection was non-properly terminated
body: <p>I'm preparing to install <a href="https://github.com/valloric/youcompleteme" rel="noreferrer">vim plugin</a> by  vundle, after I set the vimrc</p>
  
  <pre><code>set nocompatible
  filetype off
  set rtp+=~/.vim/bundle/Vundle.vim
  
  call vundle#begin()
  
  Plugin 'gmarik/Vundle.vim'

  call vundle#end()

  <p>then I input <code>:PluginInstall</code> and get the error </p>

  <p>As <a href="https://stackoverflow.com/questions/32113065/gnutls-error-110-the-tls-connection-was-non-properly-terminated">this</a> said, It seems the plugin have been downloaded despite the error. But I can't find the <code>youcompleteme</code> directory in fact.</p>
  
  <p>I also try </p>
  
  <pre><code>git clone --recursive 'git@github.com:Valloric/YouCompleteMe.git' '~/.vim/bundle/youcompleteme'
  </code></pre>
  
  <p>and get this</p>
  
  <pre><code>Cloning into '~/.vim/bundle/youcompleteme'...
  ssh: connect to host github.com port 22: Connection timed out
  fatal: Could not read from remote repository.
  </code></pre>
  
  <p>So how to solve this?</p>
