Select Your Operating System

For Arch Linux, edit /etc/pacman.conf and add the following (note that the order of repositories in pacman.conf is important, since pacman always downloads the first found package):
[home_jonathonf_mange-tout_extra_arch]
Server = https://download.opensuse.org/repositories/home:/jonathonf:/mange-tout:/extra/arch/$arch
Then run the following as root
key=$(curl -fsSL https://download.opensuse.org/repositories/home:jonathonf:mange-tout:extra/arch/$(uname -m)/home_jonathonf_mange-tout_extra_arch.key)
fingerprint=$(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_jonathonf_mange-tout_extra_arch/alsa-utils
