ls: cannot access '/etc/ros/melodic/ros.d/*.xacro': No such file or directory

You can fix it by:

sudo apt-get install -y setpriv

keey your Husky's power on and restart the service (or simply reboot)

systemctl restart ros.serivce

You should now be able to receive status from the topic /status as mentioned in the documentation.
