Help please: Network Service Discovery Disabled

[Peter Silva]

Depends on version of ubuntu...

if  >= 16.04  (with systemd as init system)

#stop the running daemon:
systemctl stop avahi.service

# prevent start in future:
systemctl disable avahi.service


I don't have earlier versions handy... but they will be different because
of upstart.

#stop the running daemon
service avahi-daemon stop

# prevent start in future:
update-rc.d avahi-daemon disable

I'm just quoting from here for the earlier versions:
