Dimitri,
I have a question about the chosen nameservers.

When using systemd 232-21-ubuntu3 or earlier, it was like this (systemd-resolve --status):
Link 2 (eth0)
      Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6
       LLMNR setting: yes
MulticastDNS setting: no
      DNSSEC setting: no
    DNSSEC supported: no
         DNS Servers: 193.210.18.18
                      193.210.19.19
          DNS Domain: dhcp.inet.fi

When using systemd 233-5ubuntu1 (manual start), it is like this (systemd-resolve --status):
Global
         DNS Servers: 8.8.8.8
                      8.8.4.4
                      2001:4860:4860::8888
                      2001:4860:4860::8844


Note the different dns servers.
The latter (8.8.8.8. ...) came from /run/systemd/resolve/resolv.conf

I think dns servers 193.210.18.18 and 193.210.19.19 are the correct ones.
Why are they different.

Title:
  On artful, no working dns after upgrading to systemd 233-5ubuntu1

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to the newest systemd 233-5ubuntu1 (in artful proposed) I got no nameserver (dns).
  This is very likely a DNS issue.
  As a workaround downgrading back to systemd 232-21ubuntu3 the network and DNS work fine.
  Or instead, I must manually start systemd-resolved:
  ~$ sudo service systemd-resolved restart

  So something odd has happened between these versions.
  Systemd-resolved is not starting automatically at boot anymore.

  My setup is a fully upgraded artful with proposed repo turned on.
  I use only Gnome DE with GDM.
  Everything else works fine, but not systemd 233-5ubuntu1.
