SYNOPSIS

flatpak install [OPTIONS] [REMOTE] REF...flatpak install [OPTIONS] [--from|--bundle] LOCATION

flatpak install installs applications or runtimes from Flatpak repositories. The REF argument specifies what to install using the format (app|runtime)/ID/ARCH/BRANCH. Typically only the application ID is needed; other parts are matched automatically or prompt for selection when ambiguous.Installation sources include configured remotes (like Flathub), .flatpakref files (application description URLs), .flatpak bundle files, or OCI images. By default, applications install system-wide; use --user for per-user installation.Dependencies (runtimes, extensions) are automatically resolved and installed. The command prompts for confirmation showing what will be downloaded and installed.

CAVEATS

System-wide installation requires root privileges or polkit authentication. Per-user installations are stored in ~/.local/share/flatpak/. Some applications require specific runtimes that will be installed automatically. Repository remotes must be configured before installing from them.

HISTORY

Flatpak was developed by Red Hat's Alexander Larsson, with the first stable release in 2015 (originally called xdg-app). It provides sandboxed application distribution independent of Linux distributions. Flathub, the primary Flatpak repository, launched in 2017 and has become the largest source of Flatpak applications.
