dietpi-services disable squeezelite [FAILED] DietPi-Services | disable squeezelite

Hi all,
I am trying to disable a service (on a pi Zero) so that I can reboot without the service temporarily. I am getting " Failed to mask unit…" and the service will be stopped but will start again on the next boot? Or how do I make this work? Thank you guys.
