Public bug reported:
Binary package hint: grub
I have always had manual kernels installed and a windows next to linux; so I
had manually altered the menu.lst file. Unaware of the implementation of
update-grub I had (mostly likely accidentally) removed the "magic marker lines"
from the menu.lst file.
(I am guessing all the the info I'm giving in this text based on reading the
update-grub code while trying to find what went wrong)
552 # Magic markers we use
553 start="### BEGIN AUTOMAGIC KERNELS LIST"
554 end="### END DEBIAN AUTOMAGIC KERNELS LIST"
The fallback behaviour on not finding the markers (which isn't there...)
is kinda harsh: you end up with a semi-empty menu.lst not containing any
kernels; while the update-grub tool tells me it has found and correctly
installed those kernels in the file (which is obviously not true).
Basically this line of code fails:
1043 sed -n -e"/$endopt/,/$end/p" < $menu > $ucf_menu_file
making also the following code "fail" leaving the ucf_menu_file empty:
1050 ucf --debconf-ok \
1051 --debconf-template grub/update_grub_changeprompt_threeway \
1052 --three-way "$buffer" $ucf_menu_file
afterwards the $buffer is deleted and thus all the found kernels are
discarded.
cheers,
Toon
