我刚刚完成 Debian buster 的全新安装，但在使用 APT 时遇到了问题。
我跑了sudo apt update，我得到了这个
Ign:1 cdrom://[Debian GNU/Linux 10.1.0 _Buster_ - Official amd64 NETINST 20190908-01:07] buster InRelease
Err:2 cdrom://[Debian GNU/Linux 10.1.0 _Buster_ - Official amd64 NETINST 20190908-01:07] buster Release
Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

我真的不明白这里有什么问题，如果这些是我在文件内进行全新安装时附带的默认源，那么我什么也没做。

注释您的deb cdrom:行并注释/删除行
deb http://deb.debian.org/debian/ buster/updates main
deb-src http://deb.debian.org/debian/ buster/updates main
并将它们替换为
deb http://deb.debian.org/debian-security/ buster/updates main
deb-src http://deb.debian.org/debian-security/ buster/updates main
我不知道这些存储库是否已更改，但这些是从Debian 维基。
或者复制并粘贴示例源.list来自 wiki，这是带有附加contrib和non-free存储库的一个
deb http://deb.debian.org/debian buster main contrib non-free
deb-src http://deb.debian.org/debian buster main contrib non-free
deb http://deb.debian.org/debian-security/ buster/updates main contrib non-free
deb-src http://deb.debian.org/debian-security/ buster/updates main contrib non-free
deb http://deb.debian.org/debian buster-updates main contrib non-free
deb-src http://deb.debian.org/debian buster-updates main contrib non-free
并再次运行sudo apt update。

我升级时遇到这个问题Debian 9 延伸至 Debian 10 Buster，我的问题是向后移植重复错误:
解决方法：
- 找到重复的行
cat /etc/apt/sources.list.d/cat /etc/apt/sources.list.d/buster-backports.list（用“YOUR-DOUBLY-CONFIGURED-FILENAME”替换“buster-backports.list”） - 使用 打开sources.list
sudo gedit /etc/apt/sources.list，找到重复的行并将其注释掉# - 保存文件并更新系统
sudo apt update
应该很好走。这Linux Mint 论坛帮助我找到了答案，也可能对你有帮助。

类似的错误，i386，Debian-10-server，没有桌面环境。我在另一台具有桌面环境的计算机上进行了类似的安装，没有出现问题。我只是编辑了 /etc/apt/sources.list 以匹配工作系统。
root@svr2:/etc/apt# cat sources.list
