Не удается запустить CUPS в Ubuntu 18.04
Я установил CUPS на Ubuntu 18.04 Bionic Beaver вот так
$ sudo apt-get update
$ sudo apt-get install cups
Я проверил статус CUPS , и он не запустился
$ systemctl status cups
● cups.service - CUPS Scheduler

Я отредактировал cupsd.conf и изменил LogLevel с «warn» на «debug». Я попытался запустить чашки вручную, но результат повторяется
$ systemctl start cups
$ systemctl status cups
Вот журнал, показанный блок повторяется.
$ grep cups /var/log/syslog

Кто-нибудь знает, как я могу запускать кубки?

Глядя на хвост /var/log/cups/error_log:
X [14/Jul/2020:15:06:38 +0200] No valid Listen or Port lines were found in the configuration file.
Действительно, файл конфигурации был испорчен некоторыми другими настройками, но, к счастью, резервная копия была сохранено:
ll /etc/cups/cupsd.conf*
-rw-r----- 1 root 4571 2020-07-01 19:53 /etc/cups/cupsd.conf.O
-rw-r----- 1 root 22 2020-07-01 19:54 /etc/cups/cupsd.conf
Это сработало для меня (в Ubuntu 18.04), чтобы восстановить cupsd.conf и перезапустить чашки:
sudo -i
cd /etc/cups
cp cupsd.conf.O cupsd.conf
systemctl restart cups
проверить по:
systemctl status cups
