I think the bug appears when I install pyopenssl. Can somebody else check whether the following shows the warning?

$ sage -pip install pyopenssl
$ sage -q
sage: quit
$

The above can be reverted with

$ sage -pip uninstall pyopenssl

Hi Vincent,

I've installed Sage 8.0 on Ubuntu 16.04 from a fresh git clone and without
any optional package (i.e. just performing make after the git clone). I do
not get any deprecation warning when quitting.

Best regards,

Eric.

Hello,

After an upgrade to sage 8.0 on Ubuntu, if I launch Sage and quit I see
the following warning

quasar:~$ sage -q
sage: quit
Exiting Sage (CPU time 0m0.04s, Wall time 0m0.76s).
/home/vdelecro/sage_patchbot/local/lib/python2.7/site-packages/twisted/protocols/tls.py:41:

DeprecationWarning: OpenSSL.rand is deprecated - you should use
os.urandom instead
    from OpenSSL.SSL import Error, ZeroReturnError, WantReadError
quasar:~$

Does anybody has an idea where it might come from? It is the source of
~20 doctest failures. Note that I installed most of the optional packages.

I am right now recompilong from scratch to see and will do a full test
suite without packages and with all optional packages.

Vincent
