Which Linux distribution has the best community?

Archlinux has the best wiki, followed by Gentoo. Honestly, though, they're all so similar that it makes no difference as long as you know where to find the docs for your distro's packaging system. This is not only true today, it was true when I got started 20 years ago as a dumb kid. The differences are almost all very superficial.

If you just want a Linux social experience, maybe join your local LUG?

I don't think there's a best community, but there might be one that best fits a particular set of values.

I like that NixOS folk treat "build a Linux distribution" as a software engineering problem: building abstractions with a language; declarative interface; large scale changes; automation; integration tests on PR; shared ownership over strong maintainership.

No data to back it up, but from my noob experience, it’s Ubuntu. Google any Linux issue and add Ubuntu as a search term and you have a higher probability of finding a solution. If you look at GitHub repos, they will almost always have Ubuntu/Debian instructions.

I think could be Raspbian, if it’s a valid reply. Not because it’s the best but because there’re millions of users and tutorial for Raspberry PI and RaspbianOS. (PS: I use and prefer DietPI over RaspbianOS)

It’s so subjective as to make the question meaningless, but: to me the gentoo irc community is so good that sometimes I ask them questions that I know not to be distro-dependent when I use other distros.

Tough question since I haven’t switched distros that much. I think Debian has a good distro and good community.

I would wager that the Arch and Gentoo communities are also probably good.

ArchLabs takes the cake hands down in my opinion

Slackware has a small but good community on linuxquestions.org

Ubuntu

arch because the memes
