ubiquity crashed with AttributeError in keyboard_variant_timeout(): 'NoneType' object has no attribute 'apply_keyboard'

good

I have a tentative fix for this one, waiting for confirmation from someone else affected by the bug.

This bug was fixed in the package ubiquity - 2.9.24

ubiquity (2.9.24) precise; urgency=low

  * webcam:
    - image-capture-encoder is deprecated, just drop it for now
    - gst_caps_new_simple needs to use a supported width/height,
      going with 640x480 as it seems standard for most webcams.
      (LP: #942030)
  * ubi-console-setup: On automatic install, don't wait 600ms or
    dbfilter will be None by the time the timer reaches 0 (LP: #944614)
  * debian/control: Add an explicit dependency on realpath to prevent
    check-missing-firmware from crashing. In d-i, realpath is provided
    by busybox.

Please stop messing with this bug report.

Thanks

Fix released or not? Installed daily build, and had this error on first boot up.

This could still reproduced by 12.10 installer ,
step to reproduce:
1. install from 12.10 installation disk
2. At "Where are you?" page press continue.
3. At "Keyboard layout" page press continue.
4. At "Who are you?" page , quick press back twice.
5. ubiquity crashed.

Failed rate: 3/3, 100%

a proposed patch is committed in https://code.launchpad.net/~timchen119/ubiquity/ubiquity.lp944614/+merge/135580

Stephane, was this refixed or not? Can you please check and either commit fixes for raring and/or precise and/or close the bug and associated merge proposals.

I commited a fix for this to Ubiquity trunk.

This isn't based on any of the patches that have been proposed so far but instead does the "right" thing which is to cancel all timeouts when moving away from the console-setup page.

Copying the fix to the precise branch.

This bug was fixed in the package ubiquity - 2.13.13

---------------
ubiquity (2.13.13) raring; urgency=low

  [ Dmitrijs Ledkovs ]
  * Bump Standards version and override some lintian tags (ubiquity is
    weird).
  * Override expander style, which is hardcoded in light-themes to a
    light color. (LP: #1100922)
  * Consolidate CssProvider and add make minimal progress bar width 10px,
    in preparation for dot-progress of all steps.
  * Fix colour unit test, the green is no longer what it used to be...
  * Switch to "NotShowIn=KDE" for ubiquity-gtk desktop files, as most !kde
    desktop environments use gtk frontend.
  * Show progress dots for plugin pages and show progress bar only during
    slideshow.

  [ Colin Watson ]
  * Decode the output of apt_pkg.size_to_str() if necessary when
    substituting it into Unicode strings (LP: #877756, #1132918).
  * Update translations from Launchpad.

  [ Aurélien Gâteau ]
  * Turns the Ubiquity KDE window into a regular window and rework
    the layout of widgets to provide more space to the main content.
    The labels on the left now wrap to the next line if they are too long,
    ensuring they are never truncated.
  * KDE: Improve the layout of Prepare step
  * KDE: fix integration of the webview responsible for showing the slideshow
  * KDE: fix various issues with right-to-left languages

  [ Julien Lavergne ]
  * Use feh to draw the wallpaper on Lubuntu when using ubiquity-dm.

  [ Ma Jun (Kylin Team) ]
  * Fix referencing variable before assignment (LP: #945027)

  [ Kobe Lee ]
  * Show OS column in manual partitioning page. (LP: #1100694)

  [ Stéphane Graber ]
  * Fix crash in ubi-console-setup when quickly moving back and worth between
    pages. (LP: #944614)

  [ Jonathan Riddell ]
  * Add back compositing to kwin on live CD (in ubiquity-dm), whatever was wrong
    in 2008 should be fixed now and its making us look ugly
