Note: Not a developer.
Jami can be installed with:
- Terminal commands.
- DEB and RPM installation files.
It is unsure why Snaps are officially supported, as dropping official support for Snaps might enable developers to allocate their time packaging Jami using Snaps to improving the Jami application.
The following image is from the Beyond APT: Software Management with Flatpak on Ubuntu | Linux Journal page.
Possible reasons the Jami team may support Snaps and not Flatpak:
- Snaps has support for desktops, IoT (Internet of Things), and servers.
- Snaps are harder for the community to build.
- Flatpaks can be built by the community.
- There is a client who requires, and pays for, Snap support.
