NetworkManager on Debian says: Device not managed

Just upgraded NetworkManager and nm-applet among other things and got this in the nm-applet popup that normally displays the available networks:

device not managed

The fix is in this Debian bug report:

  1. Either (a) edit /etc/network/interfaces to comment out the interfaces you want NetworkManager to handle or (b) change managed=false to managed=true in /etc/NetworkManager/nm-system-settings.conf.

  2. sudo killall nm-system-settings

(It doesn't look like you need to bounce /etc/init.d/networking or /etc/init.d/network-manager—I tried those but that nm-system-settings process is what you really need to kill.) If you can read this the Debian laptop is back on the net.

Thanks!
I've been wondering why network-manager wasn't working for months. This fix works like a charm.
