From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Cool, thanks for the explanation.
Does that mean that if I were to install Application A and Application B that both have dependency to package C version 1.2.3 I then would have package C (and all of its possible sub dependencies) twice on my disk? I don't know how much external dependencies applications on Linux usually have but doesn't that have the potential to waste huge amounts of disk space?
Essentially yes, if you start using lots if older applications or mixing applications that use many different dependency versions, you will start to use lots of extra disk space because the different apps have to use their own separate dependency trees and so forth.
This doesn't mean it will be like 2x-3x the size as traditional packages, but from what I've seen, it could definitely be 10-20% larger on disk. Not a huge deal for most people, but if you have limited disk space for one reason or another, it could be a problem.
It CAN get pretty wild sometimes, though. For example, Flameshot (screenshotting utility) is only ~560KB as a system package, while its flatpak version is ~1.4GB (almost 2.5k times as big)
Flameshot is 3.6MB on disk according to
flatpak info org.flameshot.FlameshotWeird, the software manager (using LM 21.3) reports 1.1GB dl, 2.4GB installed (which is different from when i checked yesterday for some reason?).
flatpak installreports around 2.1GB of dependencies and the package itself at just 1.3MBEDIT: nvm im stupid, the other reply explains the discrepancy
no, that number don't reflect the shared runtimes and deduplication
Most dependencies are bundled in the "runtime" images, and it uses file deduplication to reduce the size of the dependencies, but it's still a little more than a normal package manager.
Flatpak as a dependency system that allows use of specially packaged library type flatpaks. This significantly reduces the needed disk space.
Not necessarily. GNOME and KDE dependencies and "base system" for flatpaks to run in are flatpaks themselves so apps that depend on them will not use duplicated dependencies. Storage usage may not be as efficient as using a traditional package manager but you don't install a new OS per app either.
