My system, Squeeze, cannot install the latest kernel image because

Trying to resolve this I used e2fsck to check each of the disk
partitions and e2fsck reported all the partitions clean. However, the
result of running dosfslabel /dev/hda1 results in the following output:


There are differences between boot sector and its backup.
Differences: (offset:original/backup)

[...]

Installation of linux-base still fails as described previously and
dosfslabel /dev/hda1 still gives the error message posted prevously but
e2fsck /dev/hda1 says it is clean.

So we still have to find out why the postinst script runs dosfslabel on
an ext3 partition. Looking at the script, it seems to assemble a list of
filesystems and their types by analyzing /etc/fstab. I would therefore
like to see your output for:

grep -E 'hda1|2428f3c0|vfat|msdos|ntfs' /etc/fstab

The output is:

/dev/hda1 /temp ext2 rw,user,auto 0 2
/dev/sdc /media/fuze vfat rw,user,noauto 0 0
/dev/sg1 /usbdrive vfat rw,user,noauto 0 0
/dev/sda /media/usb1 vfat rw,user,noauto 0 0

Nothing here to make the postinst script identify /dev/hda1 as a vfat
partition. (By the way, why do you have "etx2" instead of "ext3" as the
type?)

I have copied everything on /dev/hda1 and /dev/hda5 on to a backup drive
and am considering a complete reformat of /dev/hda.

I would think that it should be enough to wipe out and reconstruct the
one problematic partition.

You can try one more thing before that. Here is a list of all the
configuration files that the postinst script seems to take into account
when searching for known block devices (you can run the awk-cut
combination yourself to make sure that your version of linux-base uses
the same files):

$ awk '/my @config_files/,/^$/{if(/path =>.*\//) print $3}' /var/lib/dpkg/info/linux-base.postinst | cut -d\' -f2
/etc/fstab
/boot/grub/menu.lst
/etc/default/grub
/etc/lilo.conf
/etc/silo.conf
/etc/quik.conf
/etc/yaboot.conf
/etc/elilo.conf
/etc/default/extlinux
/etc/udev/rules.d/70-persistent-cd.rules
/etc/initramfs-tools/conf.d/resume
/etc/uswsusp.conf
/etc/crypttab
/etc/mdadm/mdadm.conf
/etc/hdparm.conf

You can check if one of these files is present on your system and
mentions /dev/hda1 as type vfat. If that should turn out to be the case
then it might be enough to remove that reference to solve your problem.
