[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.

Feb 16 22:33:53 ubuntu grub-installer: /usr/sbin/grub-setup: error: hd0,5 appears to contain a xfs filesystem which isn't known to reserve space for DOS-style boot.  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).
