[Launchpad Bug Tracker]

This bug was fixed in the package ubiquity - 2.15.20

---------------
ubiquity (2.15.20) saucy; urgency=low

  [ Colin Watson ]
  * (Build-)depend on python3-icu rather than transitional python3-pyicu.

  [ Howard Chan ]
  * Fix the new Ubuntu Studio wallpaper backdrop for ubiquity. (LP: #1229651)

  [ Dmitrijs Ledkovs ]
  * Add dependencies on python3-pam.
  * Establish a PAM session with logind "greeter" mode in ubiquity-dm,
    resolving the following bugs:
    - WiFi page not working (LP: #1178638) (LP: #1220193)
    - Sound system / a11y not available (LP: #1229416)
    - and maybe others.
  * Automatic update of included source packages: flash-kernel
    3.0~rc.4ubuntu41.

  [ Lars Uebernickel ]
  * Force ubiquity/panel to 28 pixels height. (LP: #1207890)

Bug description:
  The following exception occurred when 'Connect' button was clicked
  after entering the wireless password on 'Wireless' screen on a non-
  live session installation using saucy desktop with 20130510 image.

  Exception in GTK frontend (invoking crash handler):
  Traceback (most recent call last):

  dbus.exceptions.DBusException: org.freedesktop.DBus.GLib.UnmappedError.NmManagerError.Code4: Not authorized to control networking.

  The steps to reproduce:
  1. Boot the hardware with a saucy installation usb 
  2. Press any key when human-keyboard screen appears
  3. Leave the default 'English' language selection and click continue (any attempt to connect to wifi networks at this stage would fail with 'Not authorized to control networking' message)
  4. Click 'Continue' on the 'Preparing to install Ubuntu' screen (here the connection status to the internet would not be ticked)
  5. Now on the 'Wireless' screen, Enter the password for the known wifi network and click 'Connect'
  6. The crash could be observed at this point.
