deb-src https://mirrors.aliyun.com/debian-security/ trixie-security main contrib non-free non-free-firmware

deb https://mirrors.aliyun.com/debian/ trixie-updates main contrib non-free non-free-firmware

deb https://mirrors.aliyun.com/debian/ trixie-backports main contrib non-free non-free-firmware
deb-src https://mirrors.aliyun.com/debian/ trixie-backports main contrib non-free non-free-firmware

保存并退出（Ctrl+O → Enter → Ctrl+X）。
