Hi, All ¨

After a fix (let’s encrypt fails), Let’s Encrypt Anacron is puting this advice:

/etc/cron.daily/nethserver-letsencrypt-certs:

/usr/lib/python2.7/site-packages/josepy/util.py:9: CryptographyDeprecationWarning: Python 2 is no longer supported by the Python core team. Support for it is now deprecated in cryptography, and will be removed in the next release.
from cryptography.hazmat.primitives.asymmetric import rsa

I made let’s encrypt work thanks to this post

Soon is going to fail, ¿what can I do fo remove this warning mail?

Thanks.
