Those interested in installing Flatpak universal Linux apps on their KDE Plasma-based GNU/Linux distros, should know that Flatpak support in the Plasma Discover package manager is now more mature and ready for production. It can handle multiple Flatpak repos, as well as installing of packages from the Flathub repository. With the upcoming KDE Plasma 5.12 LTS desktop environment, Plasma Discover will support different backends, including Flatpak and Snappy, allowing users to search, download and install Flatpak and Snap apps. However, such a backend doesn’t come installed by default, so you’ll have to add it manually.
