Ubuntu 12.10 从 12.04 升级后未更新

我从 Ubuntu 12.04 升级到了 Ubuntu 12.10。升级后无法更新。软件更新程序给出以下错误:

我无法从软件中心安装任何东西;它只是要求使用这个来源,然后它只是继续查询软件源,什么也没有发生。

其内容/etc/apt/sources.list为:

答案1

我终于找到了解决 ubuntu 12.10 无法更新问题的方法。实际上是代理出了问题,所以我做了如下操作:

我跑去gksudo gedit /etc/apt/apt.conf 编辑apt.conf文件,然后

在文件中添加以下行apt.conf

Acquire::http::Proxy "false";

现在一切都像以前一样顺利。

答案2

听起来像是互联网问题。(Unable to connect to X.X.X.X:XXXX:)尝试禁用防火墙,并退出您可能正在使用的任何代理。如果这不能解决问题,我建议更改您的 DNS。您的 ISP 可能为您提供了一个不可靠的 DNS 服务器(或者您可能手动设置了一个不可靠的 DNS 服务器。;)

无论如何,要做到这一点,只需将您的 DNS 服务器设置为208.67.222.222, 208.67.220.220(即 OpenDNS;还有其他的。选择一个你喜欢的,但最重要的是,选择一个作品)如果你不知道如何操作,可以查看详细说明这里

答案3

我自己在使用 Ubuntu 12.10 时也遇到过这个问题。在尝试修复这个问题时要小心谨慎 - 我最终重新安装了 12.04 来修复我的机器。话虽如此,Launchpad 上有一个错误报告(抱歉,找不到它),解释了 Ubuntu 12.10 如何默认启用 DNS 功能 dnsdmasq,这会搞乱很多系统。本文介绍了如何禁用 dnsdmaq。http://www.ubuntugeek.com/how-to-disable-dnsmasq-in-ubuntu-12-04precise.html

文章逐字逐句摘录如下:“

您需要编辑 /etc/NetworkManager/NetworkManager.conf 文件

$ gksudo gedit /etc/NetworkManager/NetworkManager.conf

并注释掉以下行

dns=dnsmasq

#dns=dnsmasq

保存并退出文件

现在你需要使用以下命令来管理网络

$sudo restart network-manager

希望有所帮助。

答案4

在软件源配置的其他选项卡中,尝试取消选中以下内容

1. Canonical Partners (Source Code)
2. Independent (Source Code)
3. Independent

如果有效,那就太好了。但请记住定期启用这些存储库以检查它们是否已解决问题。
