The errors there look like the issue would be about NetworkManager not running. Are you sure it is started at the time? You wouldn't then have to restart nm-applet -- nm-applet does not show if it can't talk to NM.
Otherwise, I suppose there may be issues with policykit or some other authentication system: (nm-applet:6250): nm-applet-WARNING **: GDBus.Error:org.freedesktop.NetworkManager.AgentManager.PermissionDenied: Unable to determine request sender and UID. Neither PolicyKit or polkit-gnome have changed in a while. Could you please stop NetworkManager and restart it with debug logs? Steps below. sudo systemctl stop NetworkManager sudo /usr/sbin/NetworkManager --debug > ~/nm-debug.log Then attach nm-debug.log; I expect it will show some hint as to the authentication issue somewhere near the top of the log. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager-applet in Ubuntu. https://bugs.launchpad.net/bugs/1568829 Title: nm-applet icon not showing Status in network-manager-applet package in Ubuntu: New Bug description: Since I upgraded to -proposed network-manager and network-manager-gnome versions, nm-applet no longer works.
