Failed to stop fvapp-sabnzbd.service: Unit fvapp-sabnzbd.service not loaded.

My RN214 (Arm) NAsBox is in a bit of a state. I have been trying to recover from disk failure.

I probably broke something, and now when I try to reinstall sabnzbd in the terminal (as it's not an option anymore in the UI) I get the following error:

Failed to stop fvapp-sabnzbd.service: Unit fvapp-sabnzbd.service not loaded.
dpkg: error processing package sabnzbd (--purge):
subprocess installed pre-removal script returned error exit status 5

I get this error when I try:

apt-get remove --purge sabnzbd

apt-get --reinstall install sabnzbd

I think front view is confused, as the service is not running, but I can't figure out why it is insistent on trying to stop the service.

If I could fix that, I think I would be able to fix sabnzbd
