Another thing is: dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.NetworkManager / org.freedesktop.DBus.Introspectable.Introspect
Returns with the following error: Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. Usually this should be something like this: dbus-send --system --type=method_call --print-reply --dest=org.freedesktop.ModemManager1 / org.freedesktop.DBus.Introspectable.Introspect method return time=1442906750.384191 sender=:1.4 -> destination=:1.140 serial=74 reply_serial=2 string "<!DOCTYPE node PUBLIC "-//freedesktop//DTD D-BUS Object Introspection 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/introspect.dtd"> <!-- GDBus 2.45.7 --> <node> <node name="org"/> </node> " -- 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/1497975 Title: systemctl service NetworkManager reports GLib errors in status Status in network-manager package in Ubuntu: New Bug description: Ubuntu Wily (packages updated today latest): Visual: nm-applet is not showing up network not configured background: sudo systemctl status network-manager -l ● NetworkManager.service - Network Manager Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled) Active: active (running) since Mo 2015-09-21 14:07:47 CEST; 18s ago Main PID: 5605 (NetworkManager) CGroup: /system.slice/NetworkManager.service └─5605 /usr/sbin/NetworkManager --no-daemon Sep 21 14:07:47 myhost NetworkManager[5605]: <info> devices added (path: /sys/devices/virtual/net/lo, iface: lo) Sep 21 14:07:47 myhost NetworkManager[5605]: <info> device added (path: /sys/devices/virtual/net/lo, iface: lo): no ifupdown configuration found.
