Can we create a non proof-of-childs documentation to install and run properly this repo? #20636

I have tried several times to install and run this repo in a fresh ubuntu 20.04 operative system.

All the documentation I have found is outdated. And there is not an evident clear path to successfully install this repo in at least an OS.

I would like to suggest if possible, an exhaustive doc that explains how to install this repo in any Linux distribution.

snap install bitcoin-core

Alternatively, you can self-compile (./doc/build-unix.md) or use the flatpak https://flathub.org/apps/details/org.bitcoincore.bitcoin-qt
