Both scm and python script are here http://registry.gimp.org/node/25359
The python plugin works fine in Kubuntu 16.04 Gimp 2.10.2 flatpak. Even in my old 2.9.9.appimage with compat mode off.
Best guess, Is it in the Gimp 2.10 folder ~/.config/GIMP/2.10/plug-ins/ and do you have the plugin executable?
The author has an email address (muxed) in the plugin and I do know he hangs around GimpUsers.com (the forum not the mailing list) as programmer_ceds
