Why do you mean “Universal packages”?
You don’t know how to run a binary file?
GNU/Linux (like every other operating system) has binary files. So you can just run them, without having to use a “Universal package manager”
Decentralization is not okay in package management, they have made repositories and package manager to have order on the system. Having more than one package manager breaks that order.
If you REALLY need to share an “universal package”,
just use the
--static CFLAG, this will bundle the used
libraries in the binary, it’s stupid but well, isn’t that what .AppImage
