E：某些索引文件无法下载。 它们已被忽略，或者在apt-get update之后使用旧的

我的/etc/apt/sources.list包含：

 nazar_art@nazar-desctop:/etc/apt$ cat source.list deb http://security.ubuntu.com/ubuntu precise-security main universe nazar_art@nazar-desctop:/etc/apt$ cat sources.list.old deb http://archive.ubuntu.com/ubuntu precise universe nazar_art@nazar-desctop:/etc/apt$ cat source.list deb http://security.ubuntu.com/ubuntu precise-security main universe nazar_art@nazar-desctop:/etc/apt$ 

我根据这篇文章更新了如何恢复默认存储库？

但是当我运行sudo apt-get update时它调用了另一个问题我有一些像这样的输出：

 Err http://ua.archive.ubuntu.com main/restricted Sources 404 Not Found [IP: 91.189.91.13 80] Err http://ua.archive.ubuntu.com main/universe Sources 404 Not Found [IP: 91.189.91.13 80] Err http://ua.archive.ubuntu.com main/multiverse Sources 404 Not Found [IP: 91.189.91.13 80] Err http://ua.archive.ubuntu.com main/restricted amd64 Packages 404 Not Found [IP: 91.189.91.13 80] Err http://ua.archive.ubuntu.com main/universe amd64 Packages 404 Not Found [IP: 91.189.91.13 80] 

还有这个：

 W: Failed to fetch http://ua.archive.ubuntu.com/ubuntu/dists/-backports/restricted/binary-i386/Packages 404 Not Found [IP: 91.189.91.13 80] W: Failed to fetch http://ua.archive.ubuntu.com/ubuntu/dists/-backports/universe/binary-i386/Packages 404 Not Found [IP: 91.189.91.13 80] W: Failed to fetch http://ua.archive.ubuntu.com/ubuntu/dists/-backports/multiverse/binary-i386/Packages 404 Not Found [IP: 91.189.91.13 80] E: Some index files failed to download. They have been ignored, or old ones used instead. 

更新：

我做了这个命令（谢谢NikTh）：

find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;

整体输出：

Answer 1

• 如何在Ubuntu 12.04中解决这个问题

打开终端（CTRL + ALT + T）并按顺序发出以下命令。

解：

 sudo cp /etc/apt/sources.list ~/ sudo wget "http://pastebin.com/raw.php?i=uzhrtg5M" -O /etc/apt/sources.list sudo apt-get update sudo rm /etc/apt/sources.list.d/ubuntu-extras.list sudo apt-get update 

这种解决方案并不通用。 它特定于原始海报的sources.list文件。

第二个命令以wget下载开始，并用特定的Precise（Ubuntu 12.04）sources.list文件替换sources.list文件。 访问此页面，以原始格式查看文件。

第四个命令删除了与另一个文件有冲突/冲突的ubuntu-extras.list file ，因此我们将其删除以避免错误

 W: Duplicate sources.list entry 

见上面的评论。

Answer 2

这意味着无法访问这些来源：

 http://ua.archive.ubuntu.com/ubuntu/dists/-backports/restricted/binary-i386/Packages http://ua.archive.ubuntu.com/ubuntu/dists/-backports/universe/binary-i386/Packages http://ua.archive.ubuntu.com/ubuntu/dists/-backports/multiverse/binary-i386/Packages 

尝试选择另一台服务器（不是乌克兰的服务器）。
