update from 7.10 to 8.04 doesn't update grub default correctly
Binary package hint: grub
This might be the same as #103297, but it didn't happen to me during kernel updates for 7.10.
When updated to 8.04 using the update manager, the default index was left unchanged, which was an error.
This is a dual-boot machine, with the default set to the windows entry (#4 in 7.10). Upon upgrading to 8.04, this needed to be changed to #6 in order to refer to the same entry, but was left at #4, which defaulted to the memtest86 entry. That would be very confusing indeed for grandma.
The menu.lst for 8.04 had two different ubuntu kernels (plus a rescue mode for each) instead of one kernel, which is why the index was off by 2.
Also, this machine was subject to another (totally separate) bug which causes ubuntu to fail to boot they 8.04 kernel without a modification to the kernel parameters.
If the update process was intending to modify menu.lst *after* the first reboot, this could explain why it failed.
If this is not a duplicate of a known bug, I can submit my menu.lst and any other information that would be useful. Thanks.
