How to remove lighttpd from startup in Ubuntu 15.04?

Question

linux

The task is to start the server manually (sudo service lighttpd start/stop).
The command 'sudo update-rc.d -f lighttpd remove' doesn't work, after restarting the computer the server is active. What can be removed?

Answer 1

sudo update-rc.d lighttpd disable

Answer 2

Both answers work (systemctl disable lighttpd, sudo update-rc.d lighttpd disable),
but now I can't start the server after rebooting with
sudo service lighttpd start
