I am happy that we were able to get this resolved for you. I'm going to go ahead and convert this report to a question, because this is more of a support request than a bug in the release-upgrader. From here we can mark the issue as "Solved" so that others with similar issues are able to easily find it.

Solution from the original bug report:
"Hi Tony, thank you for taking the time to submit this bug.
The log indicates several broken packages still on your system that appear to be interfering with the upgrade. Try running 'sudo apt-get remove libblas3 libpython2.7-stdlib libopenblas-base python-scipy' and then attempting the upgrade again and let me know how that goes."

Can you help with this problem?
