Censeur – Linux Application Installer

What is Censeur?

Censeur is a lightweight utility designed for Linux environments. Its primary purpose is to open software packages—especially those distributed as .flatpakref files—directly from the system’s software manager. By handling the necessary URL scheme, Censeur streamlines the process of adding new applications to a Linux desktop.

Main features

• Flatpak integration: Recognises flatpak+https URLs and forwards them to the appropriate software manager.
• Simple fallback: If the system does not support the URL scheme, Censeur guides users to download the reference file manually.
• Minimal interface: Operates silently in the background, requiring no complex configuration.

How it works

When a user clicks a link that points to a Flatpak reference, the operating system attempts to open it with the default handler. Censeur registers itself as that handler, intercepting the request and passing the reference to the installed software manager (such as GNOME Software or KDE Discover). If the manager cannot process the link, Censeur offers a clear next step: download the .flatpakref file and open it manually.

Practical uses

• Installing new applications from web pages that provide Flatpak references.
• Ensuring a consistent installation experience across different Linux distributions.
• Providing a safety net for systems where the Flatpak URL scheme is not pre‑configured.

Installation information

Censeur is typically distributed as a standard Linux package. Users can install it through their distribution’s package manager (e.g., apt, dnf, or pacman) if it is available in the repositories. Alternatively, the application may be provided as a Flatpak itself, allowing installation with a single command:

After installation, the system’s MIME database is updated so that flatpak+https links are automatically associated with Censeur.

Compatibility

Censeur works on any Linux distribution that supports Flatpak and includes a graphical software manager capable of handling .flatpakref files. Because it relies on standard desktop components, it does not require a specific desktop environment.

Things to know before installing

• Flatpak must be installed and enabled on the system for Censeur to function.
• The user’s software manager must be able to process .flatpakref files; otherwise, manual installation will be required.
• Censeur does not modify system settings beyond registering the URL handler.

Who may find Censeur useful?

Anyone who regularly installs applications from Flatpak repositories will benefit from Censeur’s seamless handling of reference links. It is especially handy for users who encounter web pages offering direct install links but lack the appropriate URL association.

Frequently asked questions

Do I need to configure anything after installing Censeur?

No additional configuration is required. The installation process updates the system’s MIME associations automatically.

What happens if my software manager cannot open the .flatpakref file?

Censeur will prompt you to download the file and open it manually, ensuring you can still proceed with the installation.

Can I uninstall Censeur without affecting other applications?

Yes. Removing Censeur restores the default handling of flatpak+https URLs, but it does not impact any applications installed via Flatpak.
