Hi again,
I tried
sudo pip install --upgrade pip
sudo pip uninstall cryptography
sudo pip install paramiko
sudo pip install cryptography -U
But to no avail unfortunately.
(elasticluster_07052019)[centos@elasticluster-final ~]$ sudo pip freeze |
grep paramiko
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020.
Please upgrade your Python as Python 2.7 won't be maintained after that
date. A future version of pip will drop support for Python 2.7.
paramiko==2.4.2
