root at bret-Inspiron-580-UbuntuMATE:/home/bret# systemctl disable
unattended-upgrades.service
Synchronizing state of unattended-upgrades.service with SysV init with
/lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install disable unattended-upgrades
insserv: warning: current start runlevel(s) (empty) of script

insserv: warning: current stop runlevel(s) (0 2 3 4 5 6) of script
