I run Debian 13 Stable with KDE Plasma, and have Flathub enabled on KDE’s Discover software store. I have a slight idea of the difference between the two: that Debian packages share system libraries and are therefore lighter in storage but do require password to access those shared libraries and could therefore become a security hazard if installing from an untrusted source, while Flatpaks have all they need and don’t require password to install, being more secure that way, but, as a consequence, consume more storage. Also noticeable is the fact that, for some programmes, the Flatpak version tends to be more recent and it therefore becomes the obvious choice when looking for the latest software.
However, I was looking at the SuperTux game, and what’s curious about this is that both, the Debian package and the Flatpak are version 0.6.3, while consuming 6.7 and 259,9 MB of storage respectively.
So should the obvious choice here be the Debian package, or would you still go for the Flatpak? I am not asking this because I’m particularly interested on this game as much as to learn more about the two system packages and whether my assumptions are correct or I am missing something.
Thank you and have a nice weekend!
Usually native packages are preferred, unless like you said you want a newer version. Some people also like the sandboxing that flatpak does if you don’t fully trust a program. The reason why the flatpak is so much bigger is because it needs to download the dependencies as well, because it can’t use the ones on your system. In this case since it’s a game it probably needs graphics drivers as well, which are fairly big i think.
