That was a painless installation. Seriously, this is something to immitate if you mean for your self-hosted application to be widely used. If only other self-hosted/distributed projects were this easy to install. I skiped on discourse, mastodon, gitlab, etc. because they were all pain to setup on a base linux system.
Not sure if you missed the official installation doc for Discourse but it recommends you to install via docker and with it, it's a 10 minute work. Not sure how faster can it be.
Sure, though I was talking about simplicity of the installation of app itself within any Linux distribution, not an entire pre-packaged Linux distribution.
