Can't install huginn with Operation not permitted (ThreadError) about huginn HOT 2 CLOSED

After adding the --privileged option in docker run command the installation goes smoothly. But this doesn't seem safe. Some people solved this here with docker version update. I checked my version and it's 19.03.15. You can see by executing apt-cache madison docker-ce that it should be the latest stable version. My system is Debian 9. So is there any better solution?

After updating Debian 9 to 10 the docker stable version was changed to 24.0.6. Docker prompt the following at the end:

To run Docker as a non-privileged user, consider setting up the Docker daemon in rootless mode for your user:
    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.
To run the Docker daemon as a fully privileged service, but granting non-root users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent to root access on the host. Refer to the 'Docker daemon attack surface' documentation for details: https://docs.docker.com/go/attack-surface/

The huginn installIton went well with no --privileged option.
Slightly different is after executing docker ps the PORTS shows 0.0.0.0:3000->3000/tcp, :::3000->3000/tcp rather than only 0.0.0.0:3000->3000/tcp on another Debian 9 server which was deployed two years ago.
