The above error renders the Ubuntu Software Centre "unusable". Upon startup the Software Centre now displays the following message:

Items cannot be installed or removed until the package catalogue is repaired.
Do you want to repair it now?

Once Update Manager has finished the repairs, you can close it and return to the store.

Stuck in a loop ...

Running this in a terminal window:

      sudo rm /var/lib/dpkg/info/libxml-libxml-perl.prerm

allowed the Ubuntu Software Centre to perform the Repair (mentioned above) successfully.
