Modifying the link to only contain one tracker url still results in an announce-list with a single entry. There also is a separate torrent file on the arch website that has the announce field set correctly. https://www.archlinux.org/releng/releases/2016.02.01/torrent/ They hide the actuall .torrent file though so addurl doesn't trigger the torrent parsing with led me to try the magnet link to begin with. Anyway, looks like aria2c is at fault because it doesn't generate standard compliant .torrent files from magnet links. """]]
