Greetings, due to Cisco's recent announcement to EOL the AireOS WLC, I wouldn't expect any open AireOS issues to be addressed. Cisco has formally invested in DNA Center modules as part of a formal Collection, and AireOS I believe is still supported:
https://galaxy.ansible.com/cisco/dnac
https://www.cisco.com/c/en/us/support/cloud-systems-management/dna-center/products-device-support-tables-list.html
https://blogs.cisco.com/networking/after-15-years-cisco-wireless-aireos-controllers-are-going-away
https://www.cisco.com/c/en/us/products/collateral/wireless/virtual-wireless-controller/eos-eol-notice-c51-744428.html
I found I had this error until I installed the Python package ansible-pylibssh (otherwise, the return string from the server would complain it was defaulting to Paramiko).
I installed the module as common user and it did not resolve the issue. Although there is no warning anymore about paramiko.
As a side note: The units willbe supprted for another 4 years. So they will not go away soon.
