Thank you. This kind of raises the bar:
"Warning: Any unofficial repository (Including arch repositories and AUR) is not supported by Artix Linux. Use them at your own risk. Packages in these repository get update at a different rate than the official repositories and may break your system. If you have any problem with your system after installing packages from these repositories, you will have to solve it yourself. If you need help, you can ask in the forum, but don't demand any help from the developers."
I need these packages to make meaningful use of my computer but enabling AUR (Arch Users Repo?) I have to cast my systems' fate to the wind. Hmmmm, not very inviting. With this warning I would have no choice but to keep an image of my updated Artix installation without AUR packages (to backlevel to in case the fan starts rattling and smelling bad) and another one of the last operational partition with AUR packages; desktop and laptop that's 4 isos.
I'm OK with giving it a try awaiting hopefully not too distant inclusion of these in the Artix repos, in light of multiple guidance fragments about HOW to do this I'd be looking for the simplest yet inclusive procedure.
How about this, is this all that's needed to enable AUR repos?
All Arch repositories are disabled by default. To enable them install artix-archlinux-support
Is editing into /etc/pacman.conf also required?
Your enabled repos in /etc/pacman.conf can, for example, look like this:
...
# Arch
[extra]
Include = /etc/pacman.d/mirrorlist-arch
Is this not done automatically, do I have to do it periodically if I want correct AUR lists?
If you need or want a more recent mirrolist, you can get a more up to date version on their github.
wget https://github.com/archlinux/svntogit-packages/raw/packages/pacman-mirrorlist/trunk/mirrorlist -O /etc/pacman.d/mirrorlist-arch
Sorry if I sound paranoid, I actually am because that's where security BEGINS. Nor do I have much faith in keyrings for the simple reason that if the word trust figures in your terminology then the only thing that is certain is that your dictionary is NOT a security dictionary.
