Ofnuts' path-grid plugin ?

Well, I use kubuntu 20.04 with Gimp 2.10.30 as https://ubuntuhandbook.org/index.php/202...ntu-20-04/ No python in that so the debs installed as previous post. Installed through apt, I think Gimp 2.10.18

If you are not using Gimp that much, an appimage is a good alternative.
