crash when trying to upgrade from yakkety to zesty

[Joe Barnett]

After clicking the 'upgrade' button in update-manager, the upgrader crashes, with the following cmdline output:

The log files attached to the bug report are from an upgrade from X to Y in September of 2016. Could you include the crash file from /var/crash/ regarding ubuntu-release-upgrader? Thanks in advance.

[Joe Barnett (thejoe)]

There is no ubuntu-release-upgrade crash file unfortunately. I ended up doing a do-release-upgrade from a terminal that did everything through the console instead of the gtk interface and that worked. possibly this is related to being in a wayland gnome session?
