当您使用 DVD 安装 Debian 10 时，如果您没有选择扫描网络镜像，Debian 操作系统安装程序会将 DVD 设置为为您的系统获取软件包的来源。 我们需要更新 来源.list 文件以便从 Internet 获取软件包。
这 /etc/apt/sources.list 以 DVD 为来源的文件将如下所示。
# # deb cdrom:[Debian GNU/Linux 10.6.0 _Buster_ - Official amd64 DVD Binary-1 20200926-10:17]/ buster contrib main deb cdrom:[Debian GNU/Linux 10.6.0 _Buster_ - Official amd64 DVD Binary-1 20200926-10:17]/ buster contrib main deb https://security.debian.org/debian-security buster/updates main contrib deb-src https://security.debian.org/debian-security buster/updates main contrib # buster-updates, previously known as 'volatile' # A network mirror was not selected during install. The following entries # are provided as examples, but you should amend them as appropriate # for your mirror of choice. # # deb https://deb.debian.org/debian/ buster-updates main contrib # deb-src https://deb.debian.org/debian/ buster-updates main contrib
如果 DVD 驱动程序中没有光盘，则在系统上安装某些软件包时，系统会要求您插入 DVD。
Media change: please insert the disc labeled 'Debian GNU/Linux 10.6.0 _Buster_ - Official amd64 DVD Binary-1 20200926-10:17' in the drive '/media/cdrom/' and press [Enter]
