Flatpak is a modern application packaging system designed for distributing desktop applications in a sandboxed environment for security and compatibility across Linux distributions.
Key benefits of Flatpak include cross-distribution compatibility, sandboxing for isolated application runs, bundling dependencies for easier installation, and version control for developers.
Limitations of Flatpak include potential storage overhead due to bundled runtimes and redundancy for Ubuntu users who already have Snap installed.
To install Flatpak on Ubuntu, users can follow simple steps like installing Flatpak through the terminal, adding the GNOME Software plugin for GUI integration, and adding the Flathub repository for access to Flatpak applications.
