In "pwsh" I need to add extension "azure-iot", but it seems I'm blocked by the check that says, "... Could not find a version that satisfies the requirement paho-mqtt==1.5.0 (from azure-iot)" Followed by the statement, "... No matching distribution found for paho-mqtt==1.5.0"

It appears the latest version of "paho-mqtt" is 1.5.1 and perhaps this is the cause of the error.

I do not know what to do. I really need the command, "az extension add --name azure-iot" to work in "pwsh" on Linux, but I don't know how to get it to work.

Do any of you guys have any ideas as to what I should try?
I hope I've provided enough information.
Thanks.

Thank you for checking that you have the latest version @UnexpectedGrit .

As per the documentation, Azure CLI is not tested in Ubuntu 21.04 version, and that can be the reason of the unexpected issue: Install the Azure CLI on Linux\Overview

Can I kindly ask that you open an issue in Azure CLI Github Repo and let me know the Link so I can follow-up with the proper team?

Thank you!
