Due to the outdated version of dhcpy6d available at Debian there is now an own dhcpy6d repository available, delivering the latest stable versions of Debian and RedHat/CentOS packages.
It works at least for Debian 10 and Ubuntu 20.04.
Add the following source to your Debian APT sources:
deb /files/repo/stable/debian/ /
Add the gpg key to your APT keyring:
wget -q -O - /files/repo/stable/debian/key.gpg | apt-key add -
To use the RedHat/CentOS 8 repository simply add the following to your repository information:
[dhcpy6d-stable]
name=dhcpy6d-stable
baseurl=/files/repo/stable/centos/
gpgcheck=1
gpgkey=/files/repo/stable/centos/RPM-GPG-KEY-dhcpy6d
enabled=1
