On Ubuntu 23.10. The issue is that gimpfu is only provided for python 2 (officially dead and out of support for 4 years!) and therefore modern(-ish) distros have dropped python 2 support in default installs. We’re in this in-between state where the latest gimp stable release (2.10.36) requires out-of-support python2.7, and the dev branch of gimp has no official stable python api. So things are a mess right now. Really puts authors of python plugins in a tight spot.
Very sad, stable boy won’t work for me 🙁
