  DEPRECATION: ws4py is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

I found a similar issue here https://github.com/Azure/azure-iot-sdk-python/issues/1182

which links to here https://github.com/psf/requests/issues/6707 and here https://github.com/msabramo/requests-unixsocket/issues/73

And the suggested workaround to downgrade requests to 2.31.0 seems to work:

(venv) kim@TAP0001367:~/pylxd$ pip install requests==2.31.0

This is a dup of #579 (fixed by #580). I'll cut a new pylxd release and upload it to pypi soon.

[kimfaint]

Thanks @simondeziel and apologies, I should have looked at Closed issues.

[simondeziel]

@kimfaint, no problem at all!

[yanksyoon]

@simondeziel Hello! May I know your schedule for releasing the fix to pypi please if possible? This would unblock https://github.com/canonical/github-runner-image-builder/pull/4 for me :D

[simondeziel]

@yanksyoon hopefully today (#582)

[simondeziel]

Done: https://pypi.org/project/pylxd/2.3.4/
