注意：我隐藏了超链接，因为我的声誉不足以在问题中包含如此多的链接。当您看到“ht tp:”时，请理解它实际上是“http:”
我认为这个问题与其他可能重复的问题不同。就我而言，我有自己的 Debian 存储库，托管我自己的 Debian 软件包，并使用 apt-get 将它们拉到客户端。
背景：这都是新问题。这不是以前能用然后坏掉的东西。这是我正在努力解决的问题。我相信这个问题是由我以某种方式错误地构建存储库引起的。
当我调用 apt-get update 时，一切似乎都很好。这些是相关行，显示 apt 已使用我的存储库 (10.1.20.65) 进行更新
$ sudo apt-get update
Get:4 ht tp://10.1.20.65/debian/ota xenial-testing InRelease [3,114 B]
Get:5 ht tp://10.1.20.65/debian/ota xenial-testing/main amd64 Packages [559 B]
当我尝试安装示例应用程序时，问题出现了：

一个明显的问题是 URL。我知道它是错的。
ht tp://10.1.20.65/debian/ota//var/www/html/debian/ota/pool/main/sample/sample_1.0-1_amd64.deb
它看起来应该是这样的：
ht tp://10.1.20.65/debian/ota/pool/main/sample/sample_1.0-1_amd64.deb
但我不知道它是如何生成的。这是我的存储库中的文件层次结构

问题：
apt 在哪里/如何获取那个“奇怪的” URL？
E: Failed to fetch ht tp://10.1.20.65/debian/ota//var/www/html/debian/ota/pool/main/sample/sample_1.0-1_amd64.deb 400 Bad Request
答案1
我找到解决办法了！
事实证明，套餐文件实际上被附加到档案根目录..我想这是由 apt-get 程序完成的。
我的档案根目录是这样的：
/var/www/html/debian/ota/
我的 Packages 文件中有这样一行：
Filename: /var/www/html/debian/ota/pool/main/sample/sample_1.0-1_amd64.deb
这些连接起来产生下载 DEB 的最终 URL：
/var/www/html/debian/ota//var/www/html/debian/ota/pool/main/sample/sample_1.0-1_amd64.deb
这种混淆是由错误的软件包文件。它不应包含绝对路径。
我的包文件中的正确路径应该是这样的：
Filename: pool/main/sample/sample_1.0-1_amd64.deb
以下是我修复的方法
之前我一直在调用apt-ftparchive 软件包 从我的二进制文件夹内：
/var/www/html/debian/ota/dists/xenial-testing/main/binary-amd64/$ apt-ftparchive packages /var/www/html/debian/ota/pool > Packages
（请注意，我必须使用绝对路径来引用水池我的 debs 的位置)
这不是构建 Packages 文件的正确文件夹。我在 Debian 的这段可爱的文字中找到了线索：
The 'packages' and 'sources' command should be run in the root of the
tree. BinaryPath should point to the base of the recursive search and
override file should contain the override flags. Pathprefix is
appended to the filename fields if present. Example usage from the
Debian archive:
apt-ftparchive packages dists/potato/main/binary-i386/ > \
dists/potato/main/binary-i386/Packages
一旦我开始以这种方式做事，我的 Packages 文件内部就开始有相对路径。
我的新命令行：
/var/www/html/debian/ota/$ apt-ftparchive packages pool/binary-amd64/ > dists/xenial-testing/main/binary-amd64/Packages
我的 Packages 文件现在包含以下行：
Filename: pool/main/sample/sample_1.0-1_amd64.deb
