Thanks for this helpful addition to ActionParsnip's comment about unused services like CUPS posing a potential security risk.
I have no intention of using CUPS now or in the future -- my system is a personal Lenovo laptop that is not part of a network of computers. Any rare printing I do is for personal use, on paper, on a Brother printer.
I just entered the disable-cups command that Rubi1200 suggested in a post above.
Can you or someone else explain to me if the return output looks right?
What does "multi-user.target.wants" stand for?
And does this mean that cups won't be coming back, not even through an ubuntu update?
Code:
sudo systemctl disable cups
[sudo] password for XXX:
Synchronizing state of cups.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install disable cups
Removed /etc/systemd/system/multi-user.target.wants/cups.service.
Removed /etc/systemd/system/multi-user.target.wants/cups.path.
Removed /etc/systemd/system/sockets.target.wants/cups.socket.
Removed /etc/systemd/system/printer.target.wants/cups.service.
