Hi, I couldn't reproduce the DNS resolution problem anymore. They both use the same deb.debian.org package repository so when I noticed this problem about ~1 month ago I ran "sudo apt update" on the 9.2.0 image it wasn't able to fetch the packages but with 9.1.0 it was. I have no idea what made it working now. Well, at least now I can start using the new 9.2 image :) Joonas
