this is all due to the fact that python 3.8 is now the latest stable release of python, sadly there is some catchup required with the developers to make their python modules 3.8 compatible, this also means certain deluge plugins (which are of course also written in python) are also not compatible with python 3.8 and thus may not work with the latest image.
