UserWarning: pkg_resources is deprecated as an API

[ajjamieson]

Describe the bug

When running az network bastion ssh commands we recieve

/.azure/cliextensions/bastion/azext_bastion/custom.py:107: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81. from pkg_resources import parse_version

This warning breaks our tooling, can the warning be silenced or the pkg_resource dependency be removed?

We've tried

1. export PYTHONWARNINGS=ignore
2. --only-show-errors
3. pip install setuptools==80.8.0 --force-reinstall

Ref (was fixed on other parts of az cli): https://github.com/Azure/azure-cli/issues/31591

Versions: azure-cli 2.75.0 core 2.75.0 telemetry 1.1.0 Extensions: azure-devops 1.0.2 bastion 1.4.1 ssh 2.0.6

Thank you for opening this issue, we will look into it.

@yonzhan, our company has a large number of developers experiencing this warning. What is the recommended course of action?

If we do not get a response in the next couple weeks, I will be submitting a ticket via azure portal to escalate.

We are experiencing it when using az artifacts. We predominantly use windows and almost all machines have the latest version of the extension and az cli.

@necusjz, @yonzhan & @aavalang: What is the status of this?

I was able to get it running again with:

$ az extension remove --name ssh
$ az extension add --name ssh

Edit: I still do get the warning, but it doesn't break. I'm able to ssh on to the VM.

It seems like the actual problem in my case was the line below the warning with No module named 'rpds.rpds'

This one disappeared after the reinstall of ssh.
