I've got this setup between two vms, where the server vm is hosting dnsmasq with ntp and the client synchronizes from the server (on a private network). This issue of the timesync conf needing to be updated exists in systemd-timesyncd too. But tackling the NetworkManager case as this is the customer issue.. we could put this fix in either networkd- dispatcher or network-manager. I've got a local build of network-manager that drops the file in place.. but needs to be tweaked.
Should the 10-update-timesyncd file be put in place by networkd- dispatcher or network-manager? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1933828 Title: NTP servers from DHCP are not propagated to timesyncd Status in OEM Priority Project: New Status in network-manager package in Ubuntu: New Status in network-manager source package in Focal: New Bug description: Network manager gets NTP servers from DHCP but do not update timesyncd to use it which keeps using ntp.ubuntu.com. This is a problem on private networks which do not have access to public internet. On this type of network the configuration of timesyncd must be updated manually instead of inheriting the conf from the dhcp servers.
