更新 1

我真的开始抓狂了。我有一个 Debian 9 系统没有互联网访问并尝试进行 apt 更新。但我总是收到相同的错误消息（见下文）。我尝试了几种允许不安全存储库的选项，但似乎没有任何效果。我很感激任何帮助。

# apt update
Ign:1 cdrom://[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25] stretch InRelease
Err:2 cdrom://[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25] stretch Release

sources.list的内容：

# cat /etc/apt/sources.list
deb cdrom:[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25]/ stretch contrib main

这是我的 apt-config，也许它可以为您提供一些帮助：

更新 2

我刚刚意识到我已经设置了 i386 多架构。我现在用 删除了它dpkg --remove-architecture i386。没有安装 i386 软件包。然后我从 删除了 DVD sources.list，并用 重新添加它，apt-cdrom. 结果保持不变。

答案1

从我看到的问题和评论来看，您唯一使用错误的是trusted选项。

您sources.list使用单行格式（参见文档)，因此使你的 cdrom 受信任的正确输入应该是：

deb [ trusted=yes ] cdrom:[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25]/ stretch contrib main

编辑：还有一些与存储库安全相关的其他选项，您可以尝试：

deb [ trusted=yes allow-insecure=yes allow-weak=yes allow-downgrade-to-insecure=yes ] cdrom:[Debian GNU/Linux 9.5.0 _Stretch_ - Official amd64 DVD Binary-1 20180714-10:25]/ stretch contrib main
