Moving to contrib ================= dbab moving to contrib is because of the Bug#1001009, first spotted by wrar then consented by nilesh, as it needs to download external files in postinst, which is not fit for main. The data is free software, however it's a living and breathing one, thus using a local copy means that - it will almost always be outdated, and - it will complicate the simple program & solution, and - it will make the core content more than doubled in size (9828 + 130499) The problem is initially spotted in 1.5.7-1 and get fixed in 1.5.7-2. Only changing to contrib section is made in d/control file, nothing else is changed, and the program behaves exactly as before. Upgrading from oldstable (buster) ================================= In case for those people that are upgrading from buster, attempts have been made to remove the following files (in debian/dbab.maintscript): /etc/dnsmasq.d/dbab.adblock.conf /etc/dnsmasq.d/dbab.trashsites.conf /etc/dbab/dbab.proxy However, due to certain limitations (see https://lists.debian.org/debian-mentors/2021/12/msg00043.html for details), they might not be able to be reliably removed. Please run the following manually after upgrade: sudo rm /etc/dnsmasq.d/dbab.adblock.conf /etc/dnsmasq.d/dbab.trashsites.conf /etc/dbab/dbab.proxy
