I managed to proceed by filtering on broken packages in synaptic and have those fixed through synaptic. After that the partial upgrade worked.
However I never attempted to reinstall packages and never noticed the debsums errors that you get. I only got the failure to upgrade ubuntu-desktop. So your mileage may vary.
