我使用以下方式维护一个合适的镜像apt-mirror. 它适用于以下软件包仿生的和焦点。现在，我想添加使用此镜像执行版本升级所需的文件。/etc/apt/mirror.list我将其添加到main/dist-upgrader-all包含这些文件夹的所有更新源中。
我的/etc/apt/mirror.list当前样子是这样的：
############# config ##################
#
set base_path /mnt/usb/ubuntu_mirror
#
# set mirror_path $base_path/mirror
# set skel_path $base_path/skel
# set var_path $base_path/var

# set defaultarch <running host architecture>
# set postmirror_script $var_path/postmirror.sh
# set run_postmirror 0
set nthreads 20
set _tilde 0

添加 之后main/dist-upgrader-all，在处理索引时执行apt-mirror会抛出以下错误：

那么，我做错了什么？如何才能成功将文件添加main/dist-upgrader-all到我的镜像中，以便使用此镜像的客户端可以执行发布升级？
答案1
该dist-upgrader-all目录不是 apt 存储库，但可以使用脚本通过 apt-mirror 进行镜像postmirror.sh。
以下几行可以添加到postmirror.sh脚本中，以镜像dist-upgrader-all焦点的目录。postmirror.sh脚本在目录中运行$base_path/mirror并使用相对路径。
mkdir -p archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/
rsync --recursive --times --links --hard-links --delete --delete-after rsync://archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/ archive.ubuntu.com/ubuntu/dists/focal/main/dist-upgrader-all/
使用 rsync 是示例postmirror.sh脚本中展示的一种技术在 apt-mirror 存储库中。它表明 rsync 可用于镜像 apt 存储库中的各种额外目录，包括debian-installer、dist-upgrader-all、installer-amd64和installer-i386路径。
