abelthorne Ah, apparemment il faut autoriser flathub : flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
JJMM jmm@jmm-FR1009610-2160084:~$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo jmm@jmm-FR1009610-2160084:~$
abelthorne Et donc, maintenant, tu devrais pouvoir installer Xnview MP : flatpak install flathub com.xnview.XnViewMP
