After installing the #933 build I was not able to select a wifi connection through the GUI because of a permissions issue. I discovered that the linaro user needed to be added to the netdev group for the UI based network selection to work correctly.
@alimon, are you aware about that?
@Loic @mcharleb The linaro user is configured to be in netdev group when Debian image is created . Occasionally at first boot/login permissions wasn’t set properly but looks like a bug in the login manager instead of not being in netdev.
