To Reproduce

1. create this simple config file:

[containers]
disable=False
all=True
podman_sock=unix:///run/user/1000/podman/podman.sock

2. Start Glances with the following options glances -C glances.ini
3. See error

Expected behavior
The glances will display running podman containers, and not errors
