Using flatpak

The official flatpak documentation should be used as reference but we will provide some basic steps for installing flatpak on the dev system:

purism@pureos:~$ sudo apt-get install flatpak flatpak-builder
purism@pureos:~$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
purism@pureos:~$ flatpak install flathub org.gnome.Platform//3.30

Note

While this documentation will direct you to the stable flatpak GNOME repository, it will be common and often required to use the gnome-nightly repository instead, for example to access the master branches of GNOME Sdk and Platform. These master branches may be required to build projects such as Calls. For more information, see the Nightly GNOME Apps page.
