Hello,  
I’ve deployed in my aks cluster AWX with awx-operator 0.28.0

It’s not a clean installation, I’m using a db from a previous AWX version (quite old version).

Now it’s working fine but I have a warning message in each jobs in AWX:

_**Identity added: /runner/artifacts/34839/ssh\_key\_data (/runner/artifacts/34839/ssh\_key\_data)**_

_ **1** _  
_ **/usr/local/lib/python3.8/site-packages/paramiko/transport.py:236: CryptographyDeprecationWarning: Blowfish has been deprecated** _

_ **2** _  
_ **“class”: algorithms.Blowfish,** _

How can I solve it? Is there any table that is causing the issue? Is it a migration problem?

Thank you for your help,  
Elia

The current version of AWX you have depends on a version of paramiko which in turn depends on the (now deprecated) Blowfish algorithm.  
paramiko has been updated[1] to fix this, but that change hadn’t made its way into the version of AWX you have installed.

Thank you for reply.  
So I have to wait a new AWX versione with the paramiko fix included. Right?

Yes, although I believe the warning is harmless in this case.
