Ulti-Maker Cura in SL-8

[robb01]

Does anyone have Cura successfully running in Sparky Linux 8?
I have an Appimage which ran successfully on the same laptop hardware under Ubuntu 22.04 but get
Failed to load module "xapp-gtk3-module"
and
Could not probe OpenGL. This program requires OpenGL 2.0 or higher. Please check your video card drivers.
I have tried versions 5.5.0 and 5.7.0 and just now 5.8.0 with the same error.
Version 5.5.0 gives a DeprecationWarning: the imp module is deprecated in favour of importlib
but his does not seem to fatal.
I also tried installing from github but get
ModuleNotFoundError: No module named 'cura'
Can anyone tell me what might be missing in Debian Trixie?
