Ubuntu – Ubuntu 14.04: Can’t connect to new password protected wifi network

network-managernetworkingwireless

After upgrading to Ubuntu 14.04 I can't connect to any new WPA2 wifi access points. Existing ones work.

Here is a pastebin of the syslog output: http://pastebin.com/QVgmRmXp

Here is an error that sometimes shows in a pop-up:

(nm-applet:28277): nm-applet-WARNING **: Connection activation failed: (1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/34' failed in libnm-glib.

There is a workaround, but it ain't pretty. When failing to connect, a file will be created here: /etc/NetworkManager/system-connections/<name of network>
If I edit that file and add a password psk=password to the [802-11-wireless-security] section, then I can connect.

  2. Click on Edit Connection which is at the bottom of the drop down.
  3. Select the network on which you want to connect, and then click edit button.
