I’m wondering if a package manager like flatpak comes with any drawback or negatives. Since it just works on basically any distro. Why isn’t this just the default? It seems very convenient.
Of course they are. they share dependencies with other software. flatpaks bundle all dependencies,which is great for sandboxing,even though some sort of break the rule and share some,they are still sandboxed.
Unless you "firejail" or "bubblewrap" your software, security is much better OOB for flatpaks.
