title: Repo init can not succeed because of GnuTLS error
body: <p>I want to get the source code of Android. To browse some blogs in the Internet, "repo init" is recommended.</p>
  
  <p>Then I use it, but it is impossible because of the following error.</p>
  
  <pre><code>android@ubuntu]~/WORKING_DIRECOTRY$ repo init -u xxxxxxxxxxxxxxxxxx
  
  Get https://gerrit.googlesource.com/git-repo
  error:GnuTLS recv error (-9): A TLS packet with unexpected length was received while accessing  https://gerrit.googlesource.com/git-repo/info/refs?service=git-upload-pack
  fatal:HTTP request failed
  </code></pre>
  
  <p>I wrote the Android source URL after "repo init -u", but I could not write the URL 
  because this site tell me that new users can only post a maximum of two hyperlinks.</p>
