[Bug 965371] Re: HTTPS requests fail on sites which immediately close the connection if TLS 1.1 negotiation is attempted, on Ubuntu 12.04

[Marc Deslauriers]

So the whole world is moving to TLS 1.1 and 1.2, and Evernote's server
isn't compatible. How is this a Ubuntu bug?

What do you propose we do? Disable TLS 1.1 and 1.2, which will prevent
Ubuntu from working with newer sites that will start requiring it, just
to fix Evernote's broken server?

Bug description:
  This week, HTTPS connections from a Python script I wrote started
  giving me this error:

  urllib2.URLError: <urlopen error [Errno 8] _ssl.c:497: EOF occurred in
  violation of protocol>

  This used to work up until some three days ago and still works on
  other Ubuntu versions, but not in other Python versions on Precise. I
  was suspecting this was a bug in Python, but a guy on AskUbuntu (
  http://askubuntu.com/questions/116020/python-https-requests-urllib2
  -to-some-sites-fail-on-ubuntu-12-04-without-proxy/116059#116059 )
  found out this happens using the openssl command line tool too:

  $ openssl s_client -connect www.mediafire.com:443

  But succeeds if forcing TLS 1 with the -tls1 argument.
