OK, my problem is fixed. After prompting by Marius - https://lists.ubuntu.com/archives/ubuntu-users/2012-September/263520.html - I finally tried the workaround noted at https://bugs.launchpad.net/ubuntu/+source/python-defaults/+bug/990740/comments/3
That is:
apt-get-install-o-APT::Immediate-Configure=false-f do-release-upgrade
worked for me.
