flatpak-https-handler

flatpak-https-handler adds support for the flatpak+https:// URL scheme used by Flathub "Install" pages.

Without a registered handler, clicking install links may do nothing on some Linux distributions. This project provides a small launcher script and a desktop entry so these links open the related .flatpakref in your software center.

On Flathub install pages (for example https://flathub.org/apps/.../install), the browser opens a flatpak+https://... URL.
This package registers a handler for that scheme so your system can open the app install flow correctly.

1. Download flatpak-https-handler_1.0_all.deb.
2. Double-click it in your file manager.
3. Click Install in your distribution's package installer.
4. Restart your browser and test a Flathub install page.

sudo dpkg -i flatpak-https-handler_1.0_all.deb

If you install via your software installer (or via apt), dependencies are handled automatically.
If you use dpkg -i and it reports missing dependencies, run:

sudo apt -f install

The post-install script automatically registers the handler for the user who ran sudo dpkg -i.
If other local users need it, each user can run:

xdg-mime default flatpak-https-handler.desktop x-scheme-handler/flatpak+https

1. Open your software/package manager.
