letsencrypt plesk problem

Filed under: Linux — Tags: , , — admin @ 4:58 pm

Well today a new problem.

I have try to install the letsencrypt  module on a plesk centos 6 server . That have python 2.6 and you will get a warning I think that is not working with python2.6 but the problem is other module.

The error’s look something like this

Fehler: Fehler bei der Installation des SSL-Zertifikats von Let’s Encrypt: Failed letsencrypt execution: /usr/local/psa/var/modules/letsencrypt/venv.gUBSl/lib/python2.6/site-packages/cryptography/__init__.py:25: DeprecationWarning: Python 2.6 is no longer supported by the Python core team, please upgrade your Python.

DeprecationWarning

ContextualVersionConflict: (cryptography 1.1 (/usr/local/psa/var/modules/letsencrypt/venv.gUBSl/lib/python2.6/site-packages), Requirement.parse(‘cryptography>=1.3’), set([‘PyOpenSSL’]))

 

The problem actually is the crypthography module.

So the fix is

cd /usr/local/psa/var/modules/letsencrypt/venv/bin

./pip install –upgrade cryptography
