It's a wonderful idea to delegate the package updates to the operating system.
ArchLinux AUR has many Julia packages already, including
julia-ijulia for notebooks
yay -S julia-distrohelper julia-loadpath
Reboot or logout/login from your user, because these 2 packages manages the julia's loadpath using system packs as a fallback. Without that Julia envs will not recognize the system installed packages.
yay -S --needed julia-ijulia nteract-bin
Now you can install any packages starting with
julia-* and notebook apps like
nteract-bin will recognize Julia as a option to notebook environments.
