If you have not enable Flathub (It will enabled by default soon) :
flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
There are two version of goldendict in Flathub:
Goldendict
flatpak install flathub org.goldendict.GoldenDict
Goldendict-ng
flatpak install flathub io.github.xiaoyifang.goldendict_ng
Or you can install either Gnome software or KDE Discover from our repository to install software (Flatpak and eopkg) graphically. As mentioned in our last sync notes, we are looking for tester. Cheers!
