Per aArch Linux, editeu /etc/pacman.conf i afegiu-hi el següent (tingueu present que l'ordre dels repositoris dins de pacman.conf és important, ja que el Pacman sempre descarrega el primer paquet que troba):
[home_jimedrand_Arch]
Server = https://download.opensuse.org/repositories/home:/jimedrand/Arch/$arch
Llavors executeu el següent com a root
key=$(curl -fsSL https://download.opensuse.org/repositories/home:jimedrand/Arch/$(uname -m)/home_jimedrand_Arch.key)
fingerprint=$(gpg --quiet --with-colons --import-options show-only --import --fingerprint <<< "${key}" | awk -F: '$1 == "fpr" { print $10 }')
pacman-key --init
pacman-key --add - <<< "${key}"
pacman-key --lsign-key "${fingerprint}"
pacman -Sy home_jimedrand_Arch/arnis
