阅读debian的说明文档，其中“5.1.1.  非自由固件在仓库中被划分到了单独的分区”描述如下：

非自由固件软件包已在仓库中被划分到了一个专门的分区，名为 non-free-firmware。为了确保已安装的非自由固件软件包能正常收到更新，您需要修改 APT 的配置。假设您仅仅需要将 non-free 分区加入 APT source-list，以便于安装固件，则修改过的 APT source-list 条目将类似于：

deb https://deb.debian.org/debian bookworm main non-free-firmware

按照上述描述，修改/etc/apt/source.list文件解决问题，文件内容如下（以阿里云为例）：
