Additional searching found that the database was apparently stored in /var/lib/nova.
I moved the database. sudo mv /var/lib/nova /var/lib/nova.old Then I purged and reinstalled nova-common sudo apt-get purge nova-common sudo apt-get install nova-common This was successful. I then ran my system updates which completed successfully. (libboost was not upgrading due to the nova-common error.) I finally removed the old database. sudo rm -frd /var/lib/nova.old Note that this solution could be employed because (to the best of my knowledge) I have yet to actually employed openstack at this time. For me this can be closed. Robert W.
