A particular method was deprecated in the Python cryptography package, 
in 2.5. See the last entry in:

https://github.com/pyca/cryptography/blob/master/CHANGELOG.rst#25---2019-01-22

The issue is not related to matplotlib. sysutils/duplicity uses 
security/paramiko, which already has a bug reported for the issue:
