这描述了如何使用图形界面修复 CD-ROM 问题：由于缺少 CDROM，无法下载存储库信息。
这是命令行版本：
编辑你的/etc/apt/sources.list。你（可能）会发现类似如下的行
deb cdrom:[Ubuntu 10.04 ...
#在那里。在每一行的开头添加一个：
# deb cdrom:[Ubuntu 10.04 ...
或者将这些行全部删除。
$ sudo apt-get update
然后就可以工作了。
还要注意，lucid 不再受支持。您将不再获得任何安全更新。我建议您升级到当前版本，例如 14.04 trusty。
如果你仍然想使用 lucid，你可以。但你必须更改/etc/apt/sources.list指向的所有条目http://old-releases.ubuntu.com/ubuntu/：
改变/etc/apt/sources.list 来自
deb http://archive.ubuntu.com/ubuntu/ ...
到
http://old-releases.ubuntu.com/ubuntu/
