Bug Description

For python-openssl Version: 0.15.1-2build1 on Ubuntu 16.04

'pip' (and other commands) importing from OpenSSL crash with the following traceback

$ pip

By googling the last line, it seems many people are experiencing this problem (an example https://stackoverflow.com/questions/43267157/python-attributeerror-module-object-has-no-attribute-ssl-st-init).

Just started hitting this as well. Simply importing the OpenSSL library raises the AttributeError:

adam@amebix:~$ python -c 'import OpenSSL'

Status changed to 'Confirmed' because the bug affects multiple users.

Changed in pyopenssl (Ubuntu):
status: New → Confirmed

I experience the same issue after upgrading from 14.04.5 to 16.04.3. Other server where 16.04.3 has been installed from fresh doesn't have the issue.

I discovered the root cause of the issue by comparing the output of `pip freeze` on both servers.

Apparently on the upgraded server cryptography-1.9 was installed in `/usr/local/python2.7/dist-packages`, while overriding python-cryptography package.

Running `sudo pip uninstall cryptography` resolves the issue.
