Unfortunately, the logs in your bug report do not show the nature of the failure. The dpkg term.log says:

Log started: 2017-07-20 23:35:56
Log ended: 2017-07-20 23:36:39

and the history.log says:

If this problem is reproducible with 'dpkg --configure -a' or 'apt -f install' from the commandline, we would need to see the output in order to understand this bug.
