Why do I receive the error "unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file..." while installing MATLAB Online Server?

Why do I receive the following error while installing MATLAB Online Server?

unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: exec-opts: (from flag: [native.cgroupdriver=systemd], from file: [native.cgroupdriver=systemd]), log-driver: (from flag: journald, from file: json-file), storage-driver: (from flag: overlay2, from file: overlay2)

By default, the Docker daemon is configured using the properties in the file /etc/docker/daemon.json, and the bootstrap-node command overwrites any customization. Unless bootstrap-node is executed with the flag –preserve-docker-config, bootstrap node creates or overwrites /etc/docker/daemon.json. If needed, run the following commands:

sudo ./mosadm merge-kube-config

which: no mosadm in (/sbin:/bin:/usr/sbin:/usr/bin)

Will merge the current config from ~/.kube/config with the one in /etc/kubernetes/admin.conf

mkdir -p /home/$USER/.kube

cp /etc/kubernetes/admin.conf /home/$USER/.kube/config

chmod 600 /home/$USER/.kube/config
