这是我第一次和Debian打交道，我需要一个docker工人。 我正在跟随https://docs.docker.com/engine/installation/linux/debian/得到它安装，但我面临的错误：
% apt-get update Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie InRelease Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie Release.gpg Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie Release Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie/contrib amd64 Packages/DiffIndex Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie/main amd64 Packages/DiffIndex Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie/contrib Translation-en_CA Ign cdrom://[Debian GNU/Linux 8.3.0 _Jessie_ - Official amd64 DVD Binary-1 20160123-19:03] jessie/main Translation-en_CA Hit http://security.debian.org jessie/updates InRelease Hit http://security.debian.org jessie/updates/main Sources Hit http://security.debian.org jessie/updates/contrib Sources Hit http://security.debian.org jessie/updates/main amd64 Packages Hit http://security.debian.org jessie/updates/contrib amd64 Packages Hit http://security.debian.org jessie/updates/contrib Translation-en Hit http://security.debian.org jessie/updates/main Translation-en Reading package lists...

Done E: Unable to locate package apt-transport-https % 更新按照build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
但是， apt-cache show apt-transport-https返回错误（无法find软件包apt-transport-https）， 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。
apt-transport-https软件包可在官方软件仓库中find（使用apt-cache show apt-transport-https ），但似乎并未包含在您用于安装的DVD中。
修改您的sources.list使用互联网存储库，而不是DVD应该修复它。 另见这里： https : //unix.stackexchange.com/questions/16370/apt-get-prompts-for-cds-when-installing-packages-how-do-i-make-it-stop
