I've raised this problem in discord and am recording it here for the team.
JingOS is missing a jingos-default-settings package which is used among other things to create the /usr/share/python-apt/templates/jingos.mirrors file which allows adding of apt repos and ppas. This is a necessary template file for add-apt-repository and other ubuntu derivates (popos, kali linux, etc) have these files in place and is the reason why it is broken currently.
