Public bug reported:
Binary package hint: ubiquity
If the "install bootloader" option is cleared (in the advanced options
on the last page of the Ubiquity installer dialogs), it appears that no
/etc/flash-kernel.conf configuration file is generated for flash-kernel
to use.
However, the linux image postinst script unconditionally runs flash-
kernel to reprogram the kernel and (I think) initrd on the SD card.
flash-kernel gets confused if there is no /etc/flash-kernel.conf; some
shell variables remain unset in flash-kernel causing odd errors.
This means that if the kernel image package (e.g., linux-
image-2.6.28-11-imx51) is upgraded, the postinst script will fail,
leaving that package half-configured. This also seems to prevent apt-get
(probably also higher-level package managers) from working until the
problem is resolved manually.
This will not affect typical users who just install with the default
configuration; however I already had a different SD card set up with a
suitable kernel for booting purposes, and wanted to avoid clobbering the
SD card with the live image on it so that I could use it again,
reproducibly.
Here's what happens when I try to upgrade the kernel image just after a clean
install:
(Actually, there's no newer package available, so I simulate this by
reinstalling the kernel image)

Poking around, I can see that there is no flash-kernel.conf (it _is_ there with
sane contents of bootloader installation was enabled)
r...@ubuntu-desktop:~# ls --color=never /etc/flash-kernel.conf
ls: cannot access /etc/flash-kernel.conf: No such file or directory
Since flash-kernel.conf is just sourced as a shell script, I can artificially
make flash-kernel "succeed" by this ugly hack (but it's obviously not the right
solution!)
