Docker rootless and user systemd stop hangs

Hello,

I've installed docker rootless from https://aur.archlinux.org/packages/dock … xtras-bin/
No special problem, is working fine. But when trying to stop the service using systemd, it hangs even after few mins (>5mins)

systemctl --user stop docker.service

Here the journalctl output

but as we can see

Jan 04 16:07:41 archi dockerd-rootless.sh[1010]: time="2021-01-04T16:07:41.205794397+01:00" level=info msg="Daemon shutdown complete"

is correctly shutdown and after any docker command failed with

Cannot connect to the Docker daemon at unix:///run/user/1000/docker.sock. Is the docker daemon running?

The main problem is that at every poweroff, I've to wait systemd unit timeout 2mins for User 1000 service

Do you have any idea why is not shutdown correctly and/or how to fix it?
