根据此处显示的信息：我无法将磁力链接与 qBittorent 关联起来打开。我收到此错误：
Failed to load info for handler 'qBittorrent.desktop'
答案1
截至目前，新的做法是：
gio mime x-scheme-handler/magnet qbittorrent.desktop
答案2
我去过这里https://unix.stackexchange.com/questions/55214/how-to-override-the-gnome-3-ssh-handler/100736#100736
打开终端输入
gvfs-mime --set x-scheme-handler/magnet qbittorrent.desktop
