Let's Encrypt Authority X3 failed renew

after updating to version 7.6 the certificate is not updated automatically.
By typing this command I get

#certbot --version
Traceback (most recent call last):
File “/usr/bin/certbot”, line 5, in
from pkg_resources import load_entry_point
File “/usr/lib/python2.7/site-packages/pkg_resources.py”, line 3011, in
parse_requirements(requires), Environment()
File “/usr/lib/python2.7/site-packages/pkg_resources.py”, line 630, in resolve
raise VersionConflict(dist,req) # XXX put more info here
pkg_resources.VersionConflict: (cryptography 1.7.2 (/usr/lib64/python2.7/site-packages), Requirement.parse(‘cryptography>=1.9’))

I solved this way

yum install python-pip
pip install --upgrade pip
pip install cryptography --upgrade
certbot --version
certbot renew

I can’t reproduce, I tested 3 different 7.6 systems.
I guess you have some customization on your system.

Anyone able to reproduce?

NS7.6 updated

[root@srv01 etc]# certbot --version
certbot 0.29.1
