I'm not sure for -s With an empty /etc/ntp.conf ntpdate is not run at all because the set -e in ntpdate-date script.
sh -x /usr/sbin/ntpdate-debian set -e + [ -r /etc/default/ntpdate ] + . /etc/default/ntpdate + NTPDATE_USE_NTP_CONF=yes + NTPSERVERS=ntp.ubuntu.com + NTPOPTIONS= + [ yes = yes ] + [ -r /etc/ntp.conf.dhcp ] + [ -r /etc/ntp.conf ] + file=/etc/ntp.conf + [ -n /etc/ntp.conf ] + sed -rne s/^(server|peer) ([-_.[:alnum:]]+).*$/\2/p /etc/ntp.conf + grep -v ^127\.127\. + NTPSERVERS= Now there's no /etc/ntp.conf in ntpdate package... And the culprit is : system-tools-backends, via gnome update time? But maybe ntpdate-date should test for -r and -s file? ** Also affects: system-tools-backends (Ubuntu) Importance: Undecided Status: Unconfirmed -- ntpdate 1:4.2.2.p4+dfsg-1ubuntu2 has a flawed configuration file. https://launchpad.net/bugs/83604 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
