in Artful we are migrating away from ifupdown to netplan. Meaning we will not be using dhcp hooks by default, and only use networkd/network- manager. I believe networkd has native support to push NTP servers to timesyncd, and I think networkmanager should natively push ntp servers direct to timesync too - without using the dhcp hooks. Adding a task for networkmanager to check this.
Native support in networkmanager would be nice; dhcp hook is thus in itself is low priority. ** Also affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Changed in: network-manager (Ubuntu) Status: New => Confirmed ** Changed in: network-manager (Ubuntu) Assignee: (unassigned) => Dimitri John Ledkov (xnox) ** Changed in: network-manager (Ubuntu) Milestone: None => ubuntu-17.09 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager 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: Confirmed Status in systemd package in Debian: New Bug description: I think it's regression for https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1578663 in zesty. 1.
