Errors in aptitude dist-upgrade from Breezy

[Janne Jokitalo]

Hello list,

I've got a slight problem dist-upgrading from Breezy to Dapper.

Whenever I'm trying to install ubuntu-desktop I get at some point this error
message:

Unpacking libgl1-mesa (from .../libgl1-mesa_6.4.1-0ubuntu8_i386.deb) ...
dpkg: error processing
/var/cache/apt/archives/libgl1-mesa_6.4.1-0ubuntu8_i386.deb (--unpack):
 unable to create `./usr/lib/libGL.so.1.2': No such file or directory
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install.  Trying to recover:
dpkg: dependency problems prevent configuration of libgl1-mesa-dri:
 libgl1-mesa-dri depends on libgl1-mesa (= 6.4.1-0ubuntu8); however:
  Package libgl1-mesa is not installed.
dpkg: error processing libgl1-mesa-dri (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 libgl1-mesa-dri

I deleted the file from from apt's cache, and tried again, but the message
is still the same. Apparently this file:

http://archive.ubuntu.com/ubuntu/pool/main/m/mesa/libgl1-mesa_6.4.1-0ubuntu8_i386.deb

is somehow faulty.

Can anyone else confirm this?
