@pengpengs can you test with the systemd versions from this ppa: https://launchpad.net/~ddstreet/+archive/ubuntu/systemd
I suspect this might be caused by bug 1849608 -- 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/1850775 Title: DNS info is not loaded by dhclient Status in network-manager package in Ubuntu: Confirmed Status in systemd package in Ubuntu: New Bug description: Hi Team, Could you please help to confirm if this is an issue on Ubuntu19.10 Desktop? 1. Update /etc/dhcp/dhclient.conf file to include below 2 new lines. supersede domain-name "vmware.com"; supersede domain-name-servers 10.117.0.1; 2. Reboot 3. check DNS info by "systemd-resolve --status", the DNS domain and server is not set. But /run/systemd/resolved.conf.d/isc- dhcp-v4-ens160.conf contains the new DNS domain and server. 4. Manually run "systemctl try-reload-or-restart systemd- resolved.service" and then DNS is set correctly, "systemd-resolve --status" output have the new DNS domain and server. I tried the same steps on Ubuntu18.04 Desktop, no such issue. DNS updated correctly after reboot.
