Hi all;

I’m trying to run the casaos script install , allmost is ok exept one step:

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

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