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

[Pablo Almeida]

Anyone knows a way to downgrade only openssl without breaking things and
without having to downgrade to 11.10? This is not an option for me,
unfortunely, and I really need this program.

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.
