package apparmor-profiles 2.13.3-7ubuntu5 failed to install/upgrade: conffile difference visualizer subprocess returned error exit status 127

Was testing the 18.04->20.04 upgrade on a small dns and dns over tls server, had edited the apparmor profile for dnsmasq to fix something a long time ago, I had tried to view the differences, and after seeing the massive change tried to accept the new version when it failed.
