Description

I'm following this for WSL2 installation. When I run podman info I got WARN[0000] Failed to detect the owner for the current cgroup: stat /sys/fs/cgroup/systemd: no such file or directory but I can pull and run Nginx image normally.

If I run with sudo the warning is gone.

Output of podman version:
