Using docker rootless context

Hi all;
I’m using docker in rootless context since few day , I uselly use docker by adding my user in docker group or as root as most of people , ans
I’m trying to run the casaos script install , allmost is ok exept one step:

[ INFO ] Updating package manager...
[  OK  ] Update package manager complete.
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

If I want to check the status docker.service , I’m doing this:

systemctl --user status docker.service

             └─14021 containerd --config /run/user/1000/docker/containerd/containerd.toml

Does somebody know if I can change something in the script ?
Thanks !
