Meant to mention this further back up the page, but the current 64-bit AppImage builds of the GIMP 2.10 (currently up to 2.10.19) can be found here, at Aferrero's GIMP continuous-build project page over at GitHub:-
https://github.com/aferrero2707/gimp-appimage/releases
As always; d/l, make executable, click to run. Simple. These contain everything required to fire-up, and just 'work'.
Enjoy.
Mike.
