I am unable to Uninstall " pip uninstall pyopenssl "

Using pip gets me this error.

Thanks in advance.

I am using

Answer 1

I did the following which seemed to fix the error, not sure if it's the correct way, but it did fix the error on my machine:

I first backed up the directories below, recommend you do same.

rm -rf /usr/lib/python2.7/dist-packages/OpenSSL
rm -rf /usr/lib/python2.7/dist-packages/pyOpenSSL-0.15.1.egg-info
sudo pip install pyopenssl

I couldn't uninstall it because every time I ran pip I got the same error you did: 'module' object has no attribute 'SSL_ST_INIT'.

After the above my pip now works and more importantly my ansible now works (which was broken by my previous updates).

Not sure if it will work on your system, and removing things out of band, like I did, is risky at best, so as a warning, I would say, your mileage may vary with my kludgy fix, use caution!

Answer 2

I ran into this issue as well. The solution proposed to run pip doesn't work because pip is broken too! I found this solved it for me:

sudo python -m easy_install --upgrade pyOpenSSL

This installed version 17.3.0 which was an upgrade to the (stock python-openssl on xenial) version ?0.15.1?. Note the massive change in version it could be they dropped the leading 0. in later versions.

Anyway, after that, pip and ansible started to work again.

Answer 3

Upgrading pyOpenSSL to 16.2.0 fixes it.

pip uninstall pyOpenSSL
pip install pyOpenSSL==16.2.0

There is an issue with version compatibility.
