我目前正在尝试离线安装软件（研究这个问题）并想根据这个答案使用离线存储库。
我按照以下步骤操作：
- 把所有债务都放进去
/var/my-local-repo sudo bash -c 'dpkg-scanpackages /var/my-local-repo /dev/null > /var/my-local-repo/Packages'（注意：dpkg-dev已安装以执行此操作）echo "deb file:/var/my-local-repo ./" > /etc/apt/sources.list.d/my-local.list通过和将存储库设置为 rootsudo apt-get update
但是当我尝试安装包时，显示以下错误：
以下是安装时终端的示例输出synaptic：

在这里我们可以看到apt 尝试从而/var/my-local-repo//var/my-local-repo/不是var/my-local-repo/
如果我将所有 deb 移动到/var/my-local-repo/var/my-local-repo/（通过创建子目录），那么在 apt 工作正常并安装包之后！
突触工作正常。
所以，我的问题是为什么 Apt 从错误的位置获取 debs 或/和需要什么更正echo "deb file:/var/my-local-repo ./"？
1 到 2 天后我自己找到了解决方案/更正并且需要更正，其工作方式如下：
如何
Packages.gz创建dpkg-scanpackages？方式一：-
如果
Packages.gz文件是通过以下命令创建的：然后它具有如下所有 debs 位置信息：
方式 2（推荐）：-
如果
Packages.gz文件是通过以下命令创建的：（换句话说，在更改到包含所有 debs 的目录之后）
然后它具有如下所有 debs 位置信息：
现在，如果
Packages.gz是由 Way-1 创建的，那么存储库 .list 中需要的更正是：deb file:/// var/my-local-repo/或者deb file:// /var/my-local-repo/但建议使用
Packages.gzWay-2 创建，无需更正，.list 中的正确存储库为：deb file:///var/my-local-repo/ ./或者deb file:/var/my-local-repo/ ./早些时候我
Packages.gz由 Way-1 创建并为第二种方式设置存储库，这就是为什么apt尝试从不需要的目录中获取 debs 的原因。Packages.gz但现在我明白了原因并使用第二种方式创建dpkg-scanpackages和最终命令是：用于生成
Packages.gz：对于设置存储库：
然后包安装成功如下：
