One significant difference between those versions is that the Debian/Ubuntu unbound package enabled query minimisation by default in package version 1.5.9-1. You might try installing 1.6.7-1ubuntu2.1 and commenting out the 'qname-minimisation: yes' line in /etc/unbound/unbound.conf.d/qname-minimisation.conf. -- Robert Edmonds edmo...@debian.org
