Looks like you just want to be able to install one of these applications.
Kicad has a flatpak which looks to be the simplest installation I can see.
flatpak install --from https://flathub.org/repo/appstream/org.kicad_pcb.KiCad.flatpakref
Easyeda has a standalone binary which looks like it would work but I haven't tested it.
