Tried to upgrade from 14.04 to 16.04. Will try to see what works after the upgrade and update this report.

There is this all over the place in the log:
insserv: script nut-client: service nut-client already provided!
insserv: script nut-client: service upsmon already provided!
insserv: script nut-client: service ups-monitor already provided!

And finally giving up on:
Setting up nut-client (2.7.2-4ubuntu1) ...
insserv: script nut-client: service nut-client already provided!
insserv: exiting now!
update-rc.d: error: insserv rejected the script header

Was there anything special in regard to your nut setup?
I see the conffile was modified, so maybe there was some tweaking to the init scripts as well?

I had no UPS around to try, but installed nut-client until it ran it with MINSUPPLIES 0 to get it running. Then I upgraded from Trusty to Xenial to see if the issue is reproducible.
But the upgrade worked and nut-client is still running fine after the upgrade.

Looking forward to your follow on update to the bug on your current status.
