Many thanks. I'm doing something wrong as I got a malformed entry. Here's what I did:
1) I went with the purge autoremove: # apt-get --purge autoremove pdns-server pdns-backend-mysql Reading package lists... Done Building dependency tree Reading state information... Done The following packages will be REMOVED: libboost-program-options1.71.0* libmysqlclient21* pdns-backend-bind* pdns-backend-mysql* pdns-server* 0 upgraded, 0 newly installed, 5 to remove and 13 not upgraded. After this operation, 21.8 MB disk space will be freed. Do you want to continue? [Y/n] Y (Reading database ... 116529 files and directories currently installed.)

Purging configuration files for pdns-backend-bind (4.2.1-1build2) ... dpkg: warning: while removing pdns-backend-bind, directory '/etc/powerdns/pdns.d' not empty so not removed Purging configuration files for pdns-server (4.2.1-1build2) ... dpkg: warning: while removing pdns-server, directory '/etc/powerdns' not empty so not removed Processing triggers for systemd (245.4-4ubuntu3.6) ... 2) I then created the suggested files (using your suggested focal-auth-44): Create the file: '/etc/apt/sources.list.d/pdns.list' with this content: deb [arch=amd64] http://repo.powerdns.com/ubuntu focal-auth-44 Created the file: '/etc/apt/preferences.d/pdns': Package: pdns-* Pin: origin repo.powerdns.com Pin-Priority: 600 3) I then executed the update & install, getting the malformed entry: # curl https://repo.powerdns.com/CBC8B383-pub.asc | sudo apt-key add - && > sudo apt-get update && > sudo apt-get install pdns-server pdns-backend-mysql % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 1682 100 1682 0 0 1990 0 --:--:-- --:--:-- --:--:-- 1988 OK E: Malformed entry 1 in list file /etc/apt/sources.list.d/pdns.list (Component) E: The list of sources could not be read. 4) Not being sure of what to do, I checked on the website https://repo.powerdns.com/ubuntu/ and noticed it is actually https://repo.powerdns.com/ubuntu/dists/. So I modified the content of /etc/apt/sources.list.d/pdns.list: deb [arch=amd64] http://repo.powerdns.com/ubuntu/dists/focal-auth-44 - and ran it again - still got a: E: Malformed entry 1 in list file /etc/apt/sources.list.d/pdns.list (Suite) I do not understand what to do here. Looking at the website, should I be using: https://repo.powerdns.com/ubuntu/dists/focal-auth-44/main/binary-amd64/Packages Also intrigued why we are using https://repo.powerdns.com/ubuntu/dists/focal-auth-44/ and not https://repo.powerdns.com/ubuntu/dists/focal-auth-master/ - maybe because it was just listed today? So what exactly does the content of the /etc/apt/sources.list.d/pdns.list file need to be? 5) Just to have a semi-functional pdns server, I removed the two files and reinstalled 4.2.1: sudo apt update && sudo apt install pdns-server pdns-backend-mysql -y Many thanks in advance.
