Confirmed. I had the same issue test upgrading from Trusty to Xenial. activate_insserv() in sysv-rc.postinst calls "insserv -v". However insserv 1.14.0-5ubuntu3 as in Xenial does not ship a suitable executable in a standard bin path. In the last merge, insserv 1.14.0-5ubuntu1's changelog says "Move insserv out of system path to disuade package maintainers from invoking it directly."
