What worked for me was clearing files out of /var/lib/dpkg/updates. ubuntu 16.04. UpdateManager.py, in refresh_cache, is hiding the underlying exception from trying to open the cache. Opening the cache asserts that there are no files in /var/lib/dpkg/updates that fit a certain regex, and that was what was failing.
