How To Install Sigil 2.4 on Ubuntu 24.10, Ubuntu 24.04, Ubuntu 22.04, Linux Mint And Derivative Systems (via Flatpak)
What is Flatpak?
Flatpak is a popular package management system designed to provide a consistent and secure way of distributing applications across various Linux distributions. Unlike Snap, which is developed and maintained by Canonical, Flatpak is an open-source project supported by the Freedesktop community.
Flatpak applications run in their own sandboxed environment, which prevents them from interfering with system files. This ensures better security and isolation while allowing applications to run on any Linux distribution that supports Flatpak.
One of Flatpak’s main advantages is its decentralized nature. Users can download applications from Flathub, the main Flatpak repository, rather than relying on distribution-specific repositories. However, just like Snap, Flatpak applications can take up more space due to their bundled dependencies.
