For Ubuntu 18.04 users sticking to the PPA build of GIMP image editor 2.10.22, now the Python Script support is back.
Since old GTK2 and Python 2 libraries being removed from Ubuntu universe repositories, the Python script support was excluded due to lack of dependencies when I was uploading the GIMP packages into PPA.
Ubuntu 18.04 was neglected, though. It meets all the dependencies to build the requested feature. So I added it back. Hope it’s not too late for you :). And the package was totally built via the rules from otto-kesselgulasch’s PPA.
