    正如@nobody 所暗示的那样，您正在下载的这些大文件来自apt-file. 根据文档，您可以通过修改/etc/apt/apt.conf.d/50apt-file.conf文件并运行来配置它/usr/share/doc/apt-file/examples/apt-file-2-update.sh。

    .deb从那里，您可以为这些文件设置本地缓存，例如：

    $ mkdir -p ~/.cache/apt-file ~/.config
$ touch ~/.cache/apt-file/dpkg-status
$ sed '/^Dir::State/ d; /^Dir::Cache/ d;' \
       /usr/share/doc/apt-file/examples/apt-file.conf \
       > ~/.config/apt-file.conf
$ cat <<EOF >> ~/.config/apt-file.conf
       Dir::State "$HOME/.cache/apt-file";
       Dir::Cache "$HOME/.cache/apt-file";
       Dir::State::status "$HOME/.cache/apt-file/dpkg-status";

    从那里你可以通过调用apt-file独立更新缓存：apt

    $ apt-file -c ~/.config/apt-file.conf update

    这是直接取自 manpage，因此可能需要进行一些调整。
