["David V." <1327610@xxxxxxxxxxxxxxxxxx>]

I have the same bug on Wily;

My network interface is called em1, it's the only one I have besides lo
It was configured that way by the ubuntu installer. This machine was installed with 15.04 then upgraded to 15.10. 
The system's locale is French, in case it's relevant.

I think the interface name is why network-manager doesn't handle it.

Title:
  No valid active connection found and Unmanaged device found

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  I am using Ubuntu Trusty 64bits, with an Openbox environment, a tint2
  panel and nm-applet started with the session.

  $ apt-cache policy network-manager
  network-manager:
    Installé : 0.9.8.8-0ubuntu7

  Here is my hardware configuration:
  Ethernet:
  00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06)

  Wifi:
  Centrino Advanced-N 6200 driver=iwlwifi driverversion=3.13.0-29-generic firmware=9.221.4.1 

  Here is the problem: when I start the X session with wireless and
  ethernet both enabled, the nm-applet does show in the panel; once I
  deactivate the wifi in nm-applet, it just disappears;

  From there it does not reconnect to Ethernet (though the cable is
  plugged in). If I reboot completely, once logged into X (I use
  lightdm), the applet still doesn't show, however when I click on the
  panel where it is supposed to be, I see the menus : left-click, right-
  click : it is a ghost applet! Left click all entries except configure
  vpn are grayed, right click lets me access to all entries, and
  information about the connections states "Erreur lors de l'affichage
  des informations de connexion :

  Aucune connexion valide active trouvée !" (Error while displaying informations about connection : no valid active connection found!") and in /var/log/syslog:
  Jun  7 21:56:33 gazelle NetworkManager[1612]: <info> Unmanaged Device found; state CONNECTED forced. (see http://bugs.launchpad.net/bugs/191889)

  (but #191889 is not the same as the one I am hitting here).

  If I use dhclient eth0 as root it will (re)connect same if I reboot
  completely.

  Thanks for fixing network-manager and it's applet!

  If you need me to bring more log files, I'll be around.

  Regards,
  Mélodie
