ubiquity crashed with permission error on NetworkManager GetDevices() call

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:
http://iso.qa.ubuntu.com/qatracker/reports/bugs/1495017

Status changed to 'Confirmed' because the bug affects multiple users.

Also occurring on Ubuntu GNOME daily image for 2015-09-11.

Fwiw the image at http://cdimages.ubuntu.com/daily-live/20150911/wily-desktop-amd64.iso appears to work.

Broken in Xubuntu, Lubuntu appears to fail at ubiquity but gives no error output.

In Vbox I also get Ubuntu failing.

I'm seeing this in the daily build I downloaded on 12 Sep 2015 at about 2200 BST (GMT+1).

The machine is a UEFI laptop with a Broadwell i7-5700HQ. Model is an MSI GT72 2QD

affects Lubuntu i386 too

I try to install daily build 15.10 (20150913) and i cannot do it because this error, but at july and august I have this system
on my notebook and it was rather well.....
My notebook always in legasy mode (not UEFFI) (Aspire S7, Intel® Core™ i7-3517U CPU @ 1.90GHz × 4 , Intel® Ivybridge Mobile
64-bit)

@junior0 what type of ubuntu are you on? This bug has now been reported for Ubuntu, Xubuntu and Lubuntu.

As a tmp workaround am installing ubuntu-gnome now using todays image using from terminal (from live session/try option-
sudo -H bash -c 'ubiquity gtk_ui'

Thanks, that does work for me with Lubuntu.

error occurs with daily build of lubuntu 15.10 (20150914) when booting with usb made with unetbootin.

Mathieu, can you please have a look? Thank you!

This appears to be "bad" code for calling up NetworkManager -- for some reason dbus-python now doesn't like the fact that we call up the object directly, not through a specified interface. Fixing this right now...

This bug was fixed in the package ubiquity - 2.21.30

---------------
ubiquity (2.21.30) wily; urgency=medium

  [ Mathieu Trudel-Lapierre ]
  * Fix access denied crashes in calling GetDevices() for NM integration: this
    happened because we didn't specify a DBus interface for the call.
    (LP: #1495017)
  * Automatic update of included source packages: grub-installer
    1.78ubuntu29.

  [ Dan Chapman ]
  * Multiple autopilot fixes:
    - Add workaround for 'Write changes to disk' dialog. (LP: #1480430)
    - Update the use_device_desc string in generated config file use for
      english install tests.
    - Fix handling of globalRect mismatches. (LP: #1479064)
    - Fixup string comparisons to properly match Ubuntu-MATE for the english
      install tests.
    - Fix the autopilot test runner for Ubuntu-GNOME and Ubuntu-MATE.

If you are unable to install image with this bug use this workaround:

1) Make sure your PC is connected to LAN or Wifi (There should be icon at top panel in right)
you can just type this command in another tty to enable network:
 # systemctl start NetworkManager

2) Run these commands in tty1
# apt-get update
# apt-get upgrade
# pkill ubiquity

3) when login appears username is ubuntu without password

Hope it works!

Works, thank you

A workaround similar to Doug McMahon´s #11: installing ubuntu studio (Ubuntu Wily Werewolf (development branch)15.10 daily build downloaded Sept 19 2015) from terminal (from live session) worked for me:

$ sudo -i
# sh -c 'ubiquity gtk_ui'

I have two questions.

1. I did NOT
# systemctl start NetworkManager
# apt-get update
# apt-get upgrade
# pkill ubiquity
as advised by Marek in #17. Will this cause me trouble? I am writing this in the installed 15.10 Beta. Maybe NetworkManager had already started correctly in another code branch - I had checked the option ¨download updates while installing¨.

2. When I wanted to add Ubuntu Studio to the affected distributions, it was not in the dropdown choices. Shouldn ´t it?

HTH, thank you Mathieu for looking into this.
