[Bug 1795852] Re: "systemd-resolve --status" reports "Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found."

[Jim Baxter]

This happened to me when I upgraded from 16.04 LTS to 18.04 LTS, I
noticed error dialog boxes during the install but unsure if they are
related.


The /etc/resolv.conf contained:

# Generated by NetworkManager
search lan
nameserver 127.0.0.53


I compared it to a fresh install of 18.04 and this had /etc/resolv.conf
as a symlink pointing to /run/systemd/resolve/stub-resolv.conf, so I
modified the broken system with these commands.

sudo mv /etc/resolv.conf /etc/resolv.conf.bak
sudo ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

But this did not work.


I then found that the broken system had the package resolvconf installed that is not installed on the new 18.04 installation so I removed it with the command:

sudo apt purge resolvconf


After a reboot my networking now works though the /etc/resolv.conf
symlink has become a file again containing:

# Generated by NetworkManager
search lan
nameserver 192.168.1.1


The command systemd-resolve --status still fails with the error:
Failed to get global data: Unit dbus-org.freedesktop.resolve1.service not found.

So I suspect this is not a correct fix but more of an accidental
workaround.

Title:
  "systemd-resolve --status" reports "Failed to get global data: Unit
  dbus-org.freedesktop.resolve1.service not found."

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  "systemd-resolve --status" reports "Failed to get global data: Unit
  dbus-org.freedesktop.resolve1.service not found."

  -> resolv.conf only holds two lines:
  --- snip

  nameserver 127.0.0.1
  --- snap

  and "host google.com" leads to
  Host google.com not found: 5(REFUSED)

  dnsmasq is running, but does not know whom to query upstream, because
  "/etc/resolv.conf" only holds the local address.

  "/etc/resolv.conf" is created by "resolvconf". Systems address is
  assigned by dhclient.

  "/etc/dhcp/dhclient.conf" holds:
  --- snip
  option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;

  send host-name = gethostname();
  request subnet-mask, broadcast-address, time-offset, routers,
          domain-name, domain-name-servers, domain-search, host-name,
          dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
          netbios-name-servers, netbios-scope, interface-mtu,
          rfc3442-classless-static-routes, ntp-servers;
  timeout 300;
  --- snap

  There are three instances of dnsmasq started:
  --- snip

  --- snap

  "/etc/network/interaces" holds:
  --- snip
  # Local loopback
  auto lo
  iface lo inet loopback
  --- snap

  What I'd expected after upgrading: working network config with a
  working "/etc/resolv.conf"!
