import paramiko throws '_sodium' has no function error

Question

Importing paramiko throws following exception on Python3.

Traceback (most recent call last):
  File "requirements_check.py", line 117, in <module>
    import paramiko
  File "/usr/local/lib/python3.5/dist-packages/paramiko/__init__.py", line 22, in <module>

AttributeError: cffi library '_sodium' has no function, constant or global variable named 'crypto_aead_chacha20poly1305_ietf_keybytes'

Does anyone know why?

Can you write which paramiko / cffi version you have installed, please? Have you build them manually? — gbajson, Apr 19 '19 at 06:28
Version: paramiko==2.4.2 I think its something to do with nacl. Nope, its a pip3 install. — jeffry copps, Apr 19 '19 at 06:34

Try uninstalling & reinstalling PyNaCl:

pip uninstall PyNaCl
pip install PyNaCl

For me, `pip uninstall PyNaCl` threw an error that it can't uninstall it '*outside environment /usr*', but `apt remove python3-nacl` then `pip install PyNaCl` did help. – Berci Feb 12 '21 at 11:23
