有谁知道如何重置source.list？

可能重复：
如何恢复默认存储库？

无论如何重置我的source.list？ 我尝试按照这个论坛http://ubuntuforums.org/showthread.php?t=1219528的技巧，但没有帮助..我想要的是，重新安装ubuntu 1204源列表。 无需通过live cd重新安装ubuntu。 并使我的操作系统像新鲜安装..任何人都可以帮助我？

谢谢

Answer 1

那你有几种方法（我很确定这个问题是重复但我找不到）：

1. 打开DASH并键入software您将看到一个显示software sources选项

   

   您将看到它将有几个选项卡，每个选项卡都会添加到sources.list的存储库行数量，例如，您有

   

   和

   

   还有

   

   您可以从中更改源文件中显示的任何内容。

2. 另一个是字面编辑文件本身。 所以打开一个终端并：

   sudo nano /etc/apt/sources.list

   并编辑你不需要的东西。 在行前添加#以将其注释掉。 它比删除它更好，以防万一你犯了错误就可以回去了。

每次更改此设置时，请始终执行sudo apt-get update以validation一切正常。 如果其中一个存储库出现问题（错误拼写，错误的符号等）， apt-get会通知您。
