I ran into the same problem upgrading Xubunut from 14.04 to 16.04, I followed Michael's steps (after trying and failing to complete the upgrade every couple of weeks), and then reran SoftwareUpdater from the Whisker Menu, and everything. Update is proceeding, I will post another comment if this does not work.
