Installing a software package in Linux can be done in a variety of ways. Package managers such as YUM for RHEL-based and APT for Debian-based distributions can be utilized. If the official repositories do not have the packages then you can use PPAs For Debian distributions or DEB or RPM packages to install them. If you choose not to use the terminal, the Software Center will make installing applications much easier. If everything else fails still you can have the option of rebuilding it from the source.
Regardless of the whole setup, there are a few obstacles to overcome. Installing from PPAs may result in errors or compatibility problems, and the software center may not always have the application you’re searching for. Furthermore, building from a source necessitates a higher level of expertise and is not much a beginner-friendly method for Linux newbies.
Given these difficulties, a universal method of installing packages is strongly advised to save time and avoid errors caused by compatibility problems. Canonical was the first person who used the snap packages to execute such an idea. Snaps are software packages that simplify the installation of software applications by being containerized, cross-distribution, and dependency-free. Flatpak, which is another universal packaging system, was introduced alongside snaps.
Flatpak is a cutting-edge method of packaging and distributing Linux desktop applications. This frees up developers to concentrate on development rather than distribution. They just need to develop the application as a Flatpak, and it will execute on any Linux distribution that supports Flatpak. Flatpak is a package manager and is comparable to Ubuntu’s Snapcraft. Ubuntu, on the other hand, owns the snap technology. That’s the reason that many Linux distributions do support Flatpak and not Snap.
That’s all about Flatpak. Now, let’s start its installation guide on Ubuntu 20.04. Firstly, ensure that you are using the terminal as a ‘superuser’.
