What is the difference between Linux package managers?
I know every distro has its own package manager, some of them share the same package manager, you can even install other package managers.
Besides the source there getting the content from, the formatting of the download and compilation phases, and maybe even a specific programming language; I still can’t wrap my head around why there need to be so many?
What rule says that every distro needs its own package and manager to install any package?
