I figured-out how to make the AppImages work on non-Ubuntu systems. I used MX Linux.
The AppImages use an 'overlay filesystem' supported by the kernel in Ubuntu. On distros like MX Linux a fuse-overlayfs is used. This must be added with 'sudo apt install fuse-overlayfs'
They are HERE.
So there is one dependency but still simple to test and use.
gimp-python2-fuse-overlay-launcher-mx-linux21-1.Appimage
gimp-python2-overlay-launcher-ubuntu22.04.AppImage
These two appimages are identical except one uses overlay and the other fuse-overlay. I have made 'full' appimages that contain a complete Gimp but not ready to upload them yet.
