In any case, the AppImage https://download.opensuse.org/repositories/home:/slowphil:/texmacs-devel/AppImage/
is probably a good option for you. It is supposed to be distro-independent, it
requires not install whatsoever and it supposedly includes all dependencies.
AFAICT it works well in Debian and Ubuntu, and it should run well in OpenSuse
because it is built with it.
