Hi Sefa, > ValueError: Namespace GnomeDesktop not available > > I am running KDE Plasma 5.14.90 (kde-unstable) and probably don't have > some default gnome dependency. I already tried installing the packages > "gnome- python" and "gnome-python-desktop", but there are for GNOME 2 > and not for GNOME 3. I don't know if this is the right answer, not knowing Python's `gi', but I did $ pkgfile -r GnomeDesktop extra/gnome-desktop $ pkgfile -l gnome-desktop | grep GnomeDesktop extra/gnome-desktop /usr/lib/girepository-1.0/GnomeDesktop-3.0.typelib extra/gnome-desktop /usr/share/gir-1.0/GnomeDesktop-3.0.gir extra/gnome-desktop /usr/share/gtk-doc/html/gnome-desktop3/GnomeDesktopThumbnailFactory.html $ ls /usr/lib/girepository-1.0 | sed 3q Atk-1.0.typelib Atspi-2.0.typelib Avahi-0.6.typelib $ It looks to me like package gnome-desktop will add the required file to /usr/lib/girepository-1.0. -- Cheers, Ralph.
