Public bug reported:
I've been testing upgrading my 15.10 and 14.04 servers to 16.04 the last
handful of weeks using do-release-upgrade -d. Up until today, it's been
fine to do so. However, when doing this on a 14.04 VM that I updated in
the same manner only yesterday I get this output after running do-
release-upgrade -d:
Traceback (most recent call last):

To clarify, this is a 14.04, completely updated VM that I have been testing
upgrading to 16.04, specifically for the best way to migrate our websites to
PHP7. I had upgraded it yesterday without trouble, but rolled back to a
previous snapshot to test a different method. Nothing on this VM has changed
on the OS side, including packages. I have no idea what's caused the breakage.
** Affects: ubuntu-release-upgrader (Ubuntu)
