Seriously though, in Debian you just type ‘sudo apt install program,’ that is about as simple as it gets.
I know apt is easy to use, but it definitely isn’t SIMPLE.
It has apt, apt-get, aptitude, synaptic and an app store as frontends, and some of them handle dependencies differently or work differently in scripts, so you need to know which to use and avoid mixing them. It has recommended and suggested dependencies. It has meta-packages, virtual packages, package groups, different repo branches seperated into categories. It has blacklisting, apt-pinning, holding back packages. You can set how aggressively it should resolve dependencies and it allows mixing releases.
I know I can do the most basic stuff with “apt update” etc. but try creating a package with dependencies for it and then maintain it across releases.
