[Bug 933433] Re: Kubuntu manual install crashed during bootloader configuration with Python stacktrace

[Andrew McDonnell]

I just had a look inside syslog, and you learn something new every day
it seems:

It would appear that installing grub onto an XFS logical partition is disallowed, and this is the underlying cause of the Python stack trace?
I believe bug is still valid however; the installer should catch the failure and not crash with the integer error message.

Installing GRUB there could result in FILESYSTEM DESTRUCTION if valuable data is overwritten by grub-setup (--skip-fs-probe disables this check, use at your own risk).

Title:
  Kubuntu manual install crashed during bootloader configuration with
  Python stacktrace

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  Reported error was "ValueError: invalid literal for int() with base
  10: '' " - a very old Ubiquity bug 42774 has same message but stack
  trace was completely different at a different point.

  Cause:

  1. Start Kubuntu CD, select 'Install' from the CD menu
  2. Do a manual partition. Drive has NTFS XP at sda2 with a rescue NTFS at sda1 and 40GB free space
  3. Added 12G XFS partition at sda5 and swap at sda6
  4. Set to install bootloader to sda5
  5. Installer progressed and copied files then died with the following stack trace on the 'Configuring Bootloader' screen

  Traceback (most recent call last):
    File "/usr/lib/ubiquity/bin/ubiquity", line 524, in <module>
      main(oem_config)
    File "/usr/lib/ubiquity/bin/ubiquity", line 511, in main
      install(query=options.query)
    File "/usr/lib/ubiquity/bin/ubiquity", line 242, in install
      ret = wizard.run()
    File "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", line 460, in run
      self.progress_loop()
    File "/usr/lib/ubiquity/ubiquity/frontend/kde_ui.py", line 863, in progress_loop
      (ret, realtb))
  RuntimeError: Install failed with exit code 1
  Traceback (most recent call last):
    File "/usr/share/ubiquity/install.py", line 2566, in <module>
      install.run()
    File "/usr/share/ubiquity/install.py", line 418, in run
      self.configure_bootloader()
    File "/usr/share/ubiquity/install.py", line 1681, in configure_bootloader
      self.db.input('critical', bootdev)
    File "/usr/lib/python2.6/dist-packages/debconf.py", line 65, in <lambda>
      lambda *args, **kw: self.command(command, *args, **kw))
    File "/usr/lib/python2.6/dist-packages/debconf.py", line 86, in command
      status = int(status)
  ValueError: invalid literal for int() with base 10: ''

  
  Digression: I should have made /boot at sda3 primary partition which would have allowed me to copy the first 512 bytes of sda3 to a bin file to chain from the XP bootloader.
