Running PureOS apps on Sailfish?

It will not run over libhybris.

The UI stack will be GTK based, with a middle ware completely from Gnome. So out of the box, no app from the librem will run on SailfishOS.

That being said, there is no fundamental issues on running their stack on SailfishOS since both are based on general GNU libraries. I'm personally very eager to work to integrate Gtk stack in SailfishOS. Some month ago Gtk was not possible due to an old version of wayland in Sailfish. @mal updated it recently. I think only QtWayland is too old now. This will be better with the Qt upgrade. So in a near future, we should be able to run Gtk also.

Being able to run (gtk) desktop applications would really be great! Especially with devices like the Gemini and Cosmo Sailfish OS would make a great convergence OS.

@Damien Caliste their apps are distributed as flatpaks. Shouldn't that take care of the GTK-libs problems? I have no idea what the other requirements for flatpak are. I reckon an relative up-to-date kernel, wayland and/or x11, and some other integration bits?

The problem is not necessary the distribution or availability of Gtk stack in SailfishOS, but more in my opinion, about the fact that Gtk can or cannot speak with the wayland compositor. Currently, it seems to me that the wayland compositor, based on QtWayland, is too old. I may be wrong though.

Lipstick is the problem? Maybe the question should be changed to: can we boot/chroot into pureOS then? I'm really not sure what the best way forward is, but as cosmo is soon shipping and there is no way jolla will provide alien dalvik for it, without modern browser sfos is sadly unusable, without android firefox to fall back onto community editions are sorely lacking, was hoping pureos browser could fill that gap
