When you use Artix Linux based on Arch Linux, and some of * Arch * Linux repositories are missing with pacman in your operation system, this post might be useful.

According to Artix Linux announcement, the repositories of [extra] / [community] are disabled by default:

Artix has reached the stage where it can operate without the help of the Arch repositories, including the preparation of its installation media.

As such, all new weekly ISO images will ship without [extra], [community] and [multilib] enabled in pacman.conf.

Here shows how to enable those repositories. Well, the detail is in Artix official wiki.

First, activate Universe repository:

# nvim /etc/pacman.conf

by appending the lines:

+ [universe]
+ Server = https://universe.artixlinux.org/$arch
+ Server = https://mirror1.artixlinux.org/universe/$arch
+ Server = https://mirror.pascalpuffke.de/artix-universe/$arch
+ Server = https://artixlinux.qontinuum.space/artixlinux/universe/os/$arch
+ Server = https://mirror1.cl.netactuate.com/artix/universe/$arch
+ Server = https://ftp.crifo.org/artix-universe/$arch
+ Server = https://artix.sakamoto.pl/universe/$arch

Then sync:

# pacman -Sy

Next, install artix-archlinux-support:

# pacman -Syu artix-archlinux-support

The output was:

==> Add the arch repos in pacman.conf:

#[testing]
#Include = /etc/pacman.d/mirrorlist-arch


[extra]
Include = /etc/pacman.d/mirrorlist-arch


#[community-testing]
#Include = /etc/pacman.d/mirrorlist-arch


[community]
Include = /etc/pacman.d/mirrorlist-arch


#[multilib-testing]
#Include = /etc/pacman.d/mirrorlist-arch


#[multilib]
#Include = /etc/pacman.d/mirrorlist-arch

==> run: 'pacman-key --populate archlinux'

Next, edit pacman.conf:

# nvim /etc/pacman.conf

to append these lines:

+ #[testing]
+ #Include = /etc/pacman.d/mirrorlist-arch
+ 
+ 
+ [extra]
+ Include = /etc/pacman.d/mirrorlist-arch
+ 
+ 
+ #[community-testing]
+ #Include = /etc/pacman.d/mirrorlist-arch
+ 
+ 
+ [community]
+ Include = /etc/pacman.d/mirrorlist-arch
+ 
+ 
+ #[multilib-testing]
+ #Include = /etc/pacman.d/mirrorlist-arch
+ 
+ 
+ #[multilib]
+ #Include = /etc/pacman.d/mirrorlist-arch

Then, run the command:

# pacman-key --populate archlinux

The output was:

==> Appending keys from archlinux.gpg...
==> Updating trust database...
gpg: next trustdb check due at 2023-07-03

That's it.
It is able now to install a package in [extra] or [community] repositories such as Deno :)
