Copy pasting random stuff from askubuntu is how you break your install in the first place. Novices don’t “have” to do that, they get told to do it by randoms on askubuntu that should not do that. Understanding an issue is key to fixing it, regardless of the problem’s nature.
I’ve yet to hit anything that worked on Ubuntu that didn’t on Mint. Hell, I find half of what I need on Arch Wiki even when not using Arch.
