When i try to connect to Podman with Podman-py 4.0.0 version :

$ python
>>> from podman import PodmanClient
>>> uri = "unix:///run/user/1000/podman/podman.sock"
>>> PodmanClient(base_url=uri).version()

I have the following error:

The above exception was the direct cause of the following exception:

Any idea ?

Not sure if this is the same issue, but I ran into this too, and it was because I didn't have podman service running, I got the exact same error, but when I try podman system service --time=0 and retry I get what I expect. Similarly starting a service with systemctl --user start podman works.

[rhatdan]

Podman service is supposed to be socket activated, could you enable the socket and see if this works.

systemctl --user enable podman.socket

Please re-open if problem continues to exist.

[nicolargo]

Confirme corrected after a restart of the service !

Thanks @naterichman
