You can install Flatpak apps on Linux without typing terminal commands, as long as Flatpak support and a repository such as Flathub are already available in your graphical software center. On GNOME desktops, use Software; on KDE Plasma, use Discover. Search for the app, make sure Flathub is selected as the source when more than one package is offered, then click Install.
The no-terminal part applies to installing apps after the graphical Flatpak integration is ready. Setup differs by distribution, so check the official Flathub setup page if Flatpak apps do not appear in your software center.
GNOME Software is designed to find, install, update, and remove applications. If your distribution has connected it to Flathub, you can install Flatpaks with a few clicks.
Open your applications menu and launch Software. The exact layout varies slightly by GNOME version and distribution, but you should see an Explore page and a search control.
Use the search box to find the application you want. A result may come from Flathub, your distribution's repository, or another enabled source. Open the result that matches the app you want.
On the app details page, look for the package source. If Software offers multiple builds, select Flathub to install the Flatpak edition. If Flathub is the only source, there may be nothing to change.
Select Install and approve any authentication prompt from your system. Flatpak may download a shared runtime or other dependencies the first time you install an app, so the initial download can be larger than the app itself. When installation finishes, launch the app from Software or your normal applications menu.
KDE Discover can manage software from several sources, including Flatpak repositories. KDE also publishes a dedicated Flatpak backend for Discover.
Open Discover, then go to Settings. If your distribution exposes the Flatpak backend here, make sure it is installed or enabled. On Kubuntu, this is the graphical setup path documented by Flathub.
In Discover's Flatpak or repository settings, confirm that Flathub is enabled. If it is missing and your distribution supports graphical setup, add the Flathub repository from Discover and restart the app if prompted.
Search for the application. If Discover lists multiple package formats, choose the result labeled Flatpak or Flathub. This avoids accidentally installing a distribution package or another format when you specifically want Flatpak.
Open the app page, verify that the source is Flathub, and click Install. Discover handles the Flatpak download and required runtimes in the background. Once complete, the application appears in your normal Plasma launcher.
You can also browse apps directly on Flathub. On desktops where .flatpakref files are associated with a compatible graphical installer, opening the downloaded file can hand the installation to your software center without requiring a terminal.
