Bug Description

Ubiquity is attempting to use x86 specific methods such as grub_default() in ubi-partman, which will not work on platforms that do not use GRUB as a bootloade r (such as ARM or PowerPC). This causes the installer to segfault and crash.

Steps to reproduce:
1. Boot a live image on non-x86
2. Start ubiquity
3. Try and do automatic or manual partitioning.

Original Bug Report:
Binary package hint: ubiquity

Had to run ubiquity manually as there is no icon on the UNE Dove image. Failure occurred when trying to select manual partitioning. Selector for manual vs automatic partitioning comes up before drive selection screen.

Tracing through the code, the problem is that ubi-partman is trying to determine the default device to partition to by calling get_grub_default which in turn calls grub_default, which tries to call some of the grub command line utilities; since these are not installed (or available) on an ARM based systme, ubiquity crashes, I suspect this bug also appears on powerpc since grub is also unavailable on that platform.

ubiquity (2.3.16) maverick; urgency=low

  [ Mario Limonciello ]
  * Don't show logout option in only-ubiquity mode(s) (LP: #618744)
  * Don't show a minimize option in only-ubiquity mode(s) (LP: #627656)
  * Translate the page_title of the language page when languages are
    swapped.
  * Restore functionality to set the GTK slideshow size based on a
    configuration file that was lost in r4123.1.37.
  * Parse the slideshow size when the GTK frontend first starts to
    prevent the window resizing later.
  * Automatic update of included source packages: grub-installer
    1.55ubuntu1, partman-basicfilesystems 63ubuntu7, partman-efi
    21ubuntu1.

  [ Evan Dandrea ]
  * Do not generate or show the bootloader options if we're on x86, or
    bootloader installation is explicitly disabled (LP: #628582).
  * Add correct URL for the Geonames service.

  [ Colin Watson ]
  * Remove a number of unused or duplicate imports.
