未能在Debian 8上安装对接器

Question

这是我第一次和Debian打交道，我需要一个码头。我跟踪https://docs.docker.com/engine/installation/linux/debian/以安装它，但是我遇到了错误：

% apt-get update
Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie InRelease

按照建议，我更新了/etc/apt/sources.list：

% cat /etc/apt/sources.list
#
deb http://ftp.de.debian.org/debian/ jessie main
deb-src http://ftp.de.debian.org/debian/ jessie main

deb http://security.debian.org/ jessie/updates main
deb-src http://security.debian.org/ jessie/updates main

deb http://ftp.de.debian.org/debian/ jessie-updates main
deb-src http://ftp.de.debian.org/debian/ jessie-updates main

然而，apt-cache show apt-transport-https返回错误(无法找到包)，and apt-get install apt-transport-https返回与以前相同的失败。

我应该看什么来解决这个问题？谢谢。

Answer 1

软件包可在官方存储库中使用(使用apt-cache show apt-transport-https检查)，但似乎没有包含在用于安装的DVD中。

修改您的sources.list以使用因特网存储库而不是DVD应该可以修复它。另见此处：https://unix.stackexchange.com/questions/16370/apt-get-prompts-for-cds-when-installing-packages-how-do-i-make-it-stop
