Hi,
the AppImage version of Phillipe Joyez works like a cham. [1]
You can find it at https://download.opensuse.org/repositories/home:/slowphil:/texmacs-devel/AppImage/
Installation instructions: [2]
1.) Download texmacs-latest-x86_x64.AppImage [3]
2.) Find the file you downloaded on your drive (usually in the
Downloads folder). Its file name starts with texmacs and ends in
.AppImage
3.) Right click the file and mark it as executable in the Permissions tab.
4.) Double click the file to start and use TeXmacs in Ubuntu
20.04 (first start takes a bit to initialize. it runs very fast,
tough.)
You can copy that file to any location on your computer and start
it by double clicking from the Files app or with the name "GNU
TeXmacs" from the launcher. [4]
Best wishes,
Ingolf
