Permissions of root partition (/dev/hda11) look OK:

# mount
/dev/hda11 on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/hda7 on /home/chris/multimedia type ext3
(rw,noexec,nosuid,nodev,errors=remount-ro)
/dev/hdb7 on /mnt/bkpb2 type ext3 (rw)

The file .deb file exists in the cache:

# ls /var/cache/apt/archives | grep xserver-xorg-core
xserver-xorg-core_2%3a1.4.1~git20080517-1_i386.deb

The file libwfb.so in the .deb seems OK:

# dpkg-deb -c /var/cache/apt/archives/xserver-xorg-core_2%3a1.4.1~git20080
0517-1_i386.deb | grep libwfb
-rw-r--r-- root/root    199392 2008-05-18 12:55 ./usr/lib/xorg/modules/libwfb.so

During install, aptitude reports this error:

Unpacking replacement xserver-xorg-core ...
dpkg: error processing
/var/cache/apt/archives/xserver-xorg-core_2%3a1.4.1~git20080517-1_i386.deb
(--unpack):
 unable to create `./usr/lib/xorg/modules/libwfb.so': No such file or directory
dpkg-deb: subprocess paste killed by signal (Broken pipe)

The old version I am trying to upgrade is xserver-xorg-core 2:1.3.0.0.dfsg. The
/usr/lib/xorg/modules/ directory is currently owner root and group root with
permissions drwxr-xr-x and does not contain any existing file libfbw.so. I
cannot find a copy of the xserver-xorg-core 2:1.3.0.0.dfsg deb to check whether
libfbw.so should exist in the old version. However, it does not exist in Etch. I
can't see any other obvious reason why libfbw.so won't be installed.

This Lenny partition is a "spare" installation I have on the same disc as my
everyday Etch installation. I am happy to experiment a bit. Perhaps, if all else
fails, I should completely uninstall xorg? What's the best way to do this?

Best regards,
