[Bug 792652] Re: ubiquity crashed with ValueError in command(): I/O operation on closed file

[Launchpad Bug Tracker]

This bug was fixed in the package ubiquity - 2.10.23

---------------
ubiquity (2.10.23) precise-proposed; urgency=low

  * Honour base-installer/kernel/altmeta when deciding which kernels to
    install or keep installed.

ubiquity (2.10.22) precise-proposed; urgency=low

  [ Dmitrijs Ledkovs ]
  * Make user-setup-encrypted-swap wait until partitioning has finished
    before attempting to adjust /target/etc/fstab. (LP: #1024343)
    (LP: #1068178)

  [ Colin Watson ]
  * Don't remove kernel headers just because we're removing signed kernel
    images of the same flavour (LP: #1070427).

ubiquity (2.10.21) precise-proposed; urgency=low

  [ Colin Watson ]
  * Fix missing parentheses that caused removable installation media
    sometimes to be selected as the default GRUB device (LP: #987418).
  * Support UEFI Secure Boot (LP: #1075181):
    - Try to install a signed kernel if base-installer asks for one, and
      don't leave signed kernels installed if it doesn't.
    - If the SecureBoot EFI variable is set, then ensure that
      grub-efi-amd64-signed and shim-signed remain installed.
    - Copy the signed kernel from /cdrom if it is not in the squashfs.  If
      there is a signed kernel there but no unsigned one, then use sbattach
      to remove the signature and construct the unsigned kernel on the fly.
  * Automatic update of included source packages: base-installer
    1.122ubuntu7.2, grub-installer 1.68ubuntu5.1.

  [ Mario Limonciello ]
  * Don't let oem-config crash from an invalid server return on the timezone
    page. (LP: #887879)

  [ Dmitrijs Ledkovs ]
  * Do not preseed grub-install, if we are not proceeding to install. This
    should fix ValueError, I/O operation on closed file (LP: #1027648)
    (LP: #792652)
  * Prevent progress label to expand & shrink the window (LP: #1046241)

  [ Jonathan Riddell ]
  * Change from a KApplication to a QApplication to avoid using DBus, DBus
    as needed by KApplication no longer works with our multiple user changes
    LP: #1055967

Bug description:
  Binary package hint: ubiquity

  I got this problem when I was trying clicking the Install Ubuntu 11.04
  from the desktop on Asus 1215B red.

  TEST CASE
  1. Boot from a Live media
  2. At Ubiquity Greeter click on 'Try Ubuntu' and start a live session
  3. Start ubiquity
  4. Proceed to step 'Prepare'
  5. Click on 'Continue' then quickly click on 'Quit' on the main dialog then 'Quit' on the confirmation dialog before the UI switches to step 'partman'

  Note:
  Timing seems important and you need to repeat steps 3 to 5 and clicking at slightly different moment until it crashes. It is easier to reproduce on low-end hardware than VM.
  Also I reproduced it more often with other languages than english.

  ACTUAL RESULT
  This crash or UI hang
