Hello, On Ubuntu desktop 22.04 LTS, it seems that the hook is not executed. I'm not sure how to verify that but sure thing is the DHCP is well announcing the ntp server.
DHCP4.OPTION[8]: ntp_servers = X.X.X.X DHCP4.OPTION[18]: requested_ntp_servers = 1 Could someone help ? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1685484 Title: DHCP exit hook for setting systemd-timesyncd NTP servers doesn't work Status in network-manager package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Won't Fix Status in systemd package in Debian: Fix Released Bug description: I think it's regression for https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1578663 in zesty. 1.

There is only one default timesyncd.conf file with default values: $ sudo find / -iname \*timesync\* /etc/systemd/timesyncd.conf /etc/systemd/system/sysinit.target.wants/systemd-timesyncd.service /etc/dhcp/dhclient-exit-hooks.d/timesyncd /usr/share/man/man5/timesyncd.conf.d.5.gz /usr/share/man/man5/timesyncd.conf.5.gz /usr/share/man/man8/systemd-timesyncd.8.gz /usr/share/man/man8/systemd-timesyncd.service.8.gz /tmp/systemd-private-d029f63116924e99b9fc44caf622e299-systemd-timesyncd.service-6NwdRT /lib/systemd/systemd-timesyncd /lib/systemd/system/systemd-timesyncd.service /lib/systemd/system/systemd-timesyncd.service.d /var/tmp/systemd-private-d029f63116924e99b9fc44caf622e299-systemd-timesyncd.service-jz0q47 $ cat /etc/systemd/timesyncd.conf # This file is part of systemd. # # systemd is free software; you can redistribute it and/or modify it # under the terms of the GNU Lesser General Public License as published by # the Free Software Foundation; either version 2.1 of the License, or # (at your option) any later version. # # Entries in this file show the compile time defaults. # You can change settings by editing this file. # Defaults can be restored by simply deleting this file. # # See timesyncd.conf(5) for details.

DHCP hook installed as /etc/dhcp/dhclient-exit-hooks.d/timesyncd is not working, TIMESYNCD_CONF=/run/systemd/timesyncd.conf.d/01-dhclient.conf is not created. 6. After manually executing steps from hook all works as expected: $ sudo mkdir -p /run/systemd/timesyncd.conf.d/ $ sudo cat <<EOF >/run/systemd/timesyncd.conf.d/01-dhclient.conf > [Time] > NTP=80.50.231.226 217.96.29.26 212.160.106.226 > EOF $ sudo systemctl try-restart systemd-timesyncd.service $ sudo systemctl status systemd-timesyncd.service * systemd-timesyncd.service - Network Time Synchronization Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled) Drop-In: /lib/systemd/system/systemd-timesyncd.service.d `-disable-with-time-daemon.conf Active: active (running) since Sat 2017-04-22 13:47:28 CEST; 2min 6s ago Docs: man:systemd-timesyncd.service(8) Main PID: 3094 (systemd-timesyn) Status: "Synchronized to time server 80.50.231.226:123 (80.50.231.226)."
