With pip on Ubuntu 14.04, I am getting this error:

Traceback (most recent call last):

SSL_ST_INIT = _lib.SSL_ST_INIT

AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

How can I solve this?

I found that this answer on stackoverflow helped. Basically, it says that you should do this:

rm -rf /home/<Your Username>/.local/lib/python2.7/site-packages/OpenSSL

sudo rm -rf usr/local/lib/python2.7/dist-packages/OpenSSL/

pip install pyOpenSSL

Use pip3

I had to switch over to using pip3 to resolve this issue:

$ sudo pip3 install --upgrade pyopenssl

yeah pip errors until you fix it manually (chicken and egg mentioned)....find where the library is installed and manually delete it.

On my 16.04 installation I did this:

cd /usr/lib/python2.7/dist-packages

rm -rf OpenSSL

Then pip worked correctly without the SSL error

pip install pyopenssl

Try this:

sudo apt-get update    

sudo easy_install -U cryptography

Then install pyopenssl package:

pip install pyopenssl

I hope this works. Cheers!

You are missing pyOpenSSL package, or is outdated.

simply run

$ pip install pyopenssl

and update packages (may not be necessary).
