[Bug 2070279] [NEW] Xubuntu 24.04 LTS installer ignores bootloader device

[Peter Lee]

Public bug reported:

Xubuntu 24.04 LTS Installer ignores specified legacy boot loader
installation device

NOTE reported against ubiquity because ubuntu-desktop-bootstrap not yet
known to launchpad

xubuntu 24.04 LTS
ubuntu-desktop-bootstrap version 0+git.eef0e0fd6 revision 205
Legacy BIOS mode installation

System is Lenovo H520S bought 2013. HDD GPT sda, SSD GPT sdb. Legacy
BIOS mode. Installing to sda13 /, sda14 /home, sda11 /boot, and
bootloader device sde, a USB thumbdrive, MBR, one empty ext2 partition.

Installer ignored specified device sde and attempts to install boot
loader on sda, which fails.

Note that first run of installer reported that updated installer was
available, update was accepted and installer restarted.

Screen photos:
	snap list showing installer version
	manual partitioning display showing sde specification
	installation summary showing bootloader going to sda not sde
	installer failure display
	installer log indicating attempt to install legacy boot loader
	  to sda failing because device is GPT not MBR

After installer failure, I was able to manually install the boot loader
to sde, and successfully booted so far as the Xubuntu login screen, but
since installer failed before user logins had been installed (and
presumably no cleanup of unneeded packages, etc, I could get no further.

This is a show-stopper for me.

Note that with the ubiquity installer, one had the option of executing
it from the command line with the -b option to tell it to skip grub
setup completely. Is there any way to do this with ubuntu-desktop-
bootstrap? (See also Launchpad bug report 696926 where a related issue
was raised after a change to ubiquity removed the choice of skipping
grub installation from the gui.)
