Please help me. I'm running openrc Artix on xfce and I can't download snap.
archlinux have officially no snap support , either artixlinux
wiki how to is here https://wiki.archlinux.org/index.php/Snap but artixlinux provide no .service replacement (you need run snapd deamon manually)
you need install "snapd" package from AUR. https://aur.archlinux.org/packages/snapd/
apparmor is provided for openrc and runit (you need install service too: apparmor-openrc or apparmor-runit). you need properly configure it and run it on boot! --> https://wiki.archlinux.org/index.php/AppArmor
completely personal note:
it amazes me that people install artixlinux because systemd is evil. But they are calmly willing to install a snap (a same evil like systemd). The snap philosophy (the program and all libraries distributed in one package ala Windows) goes against the philosophy of unix/linux (and shared libraries), not to mention the security risk of snap (non-updated libraries).
But it's your choice ;-)
To add to what
@alium mentioned, snapcrafts are bloated on size alone with the fact that AUR is better cause packages install native.
