My pamac-gtk was never updated to pamac-gtk3

I think you are mistaking a few things. :wink: pamac-gtk is the GTK4-based version of the pamac GUI, while pamac-gtk3 is the GTK3-based version.

In other words, pamac-gtk3 is an older design than pamac-gtk. GTK4 is currently only used by GNOME and GNOME applications. If you’re on XFCE, Cinnamon, MATE, Budgie or even Plasma (which is not GTK-based), then you’re better off with pamac-gtk3.

Besides, pamac-gtk — i.e. the GTK4 version — requires the installation of separate and distinct plugins for FlatPak, Snap and the AUR, while pamac-gtk3 supports all of that without any plugins.

(Edit: The latter is no longer applicable.)
