Ubuntu 14.04.4 LTS不工作的更新

Question

当我使用以下方法运行update命令时：

sudo apt-get update

我说错了：

Ign http://archive.ubuntu.com trusty/universe Translation-en_IN
Reading package lists... Done 
W: Failed to fetch http://archive.ubuntu.com|security.ubuntu.com/ubuntu/dists/trusty-security/InRelease  

W: Failed to fetch http://archive.ubuntu.com|security.ubuntu.com/ubuntu/dists/trusty-security/Release.gpg  Could not resolve 'archive.ubuntu.com|security.ubuntu.com'

W: Some index files failed to download. They have been ignored, or old ones used instead.

我的ubuntu版本是Ubuntu14.04.4LTS

我曾多次尝试使用不同的论坛来修复这个问题，但都没有成功。

请建议我怎么修理它。

您的/etc/apt/sources.list文件有问题。在源行中，不应该有任何带有in.archive.ubuntu.com|security.ubuntu.com的行。

使用以下方法保存源文件的备份：

cp -a /etc/apt/sources.list /etc/apt/sources.list.bak

然后使用sed更正当前源文件：

sed -i 's/in.archive.ubuntu.com|security.ubuntu.com/in.archive.ubuntu.com/g' /etc/apt/sources.list

紧接着是

sed -i 's/archive.ubuntu.com|security.ubuntu.com/security.ubuntu.com/g' /etc/apt/sources.list

在此之后，您的apt-get命令应该会正常工作。

实际上，我只是注意到所有的印度镜像(in.archive.ubuntu.com)都被注释掉了，这些命令已经修复了这些条目，但是它们没有被使用。

问题来自与安全更新有关的错误条目。当您更新时，您将收到安全更新，其余的更新将来自主要的Ubuntu镜像，从本地镜像(即in.archive.ubuntu.com条目)更新可能会更快。
