“sudo apt-get update”给出 404 Not found in Ubuntu 14.10

Question

我全新安装了 Ubuntu 14.10 桌面。我昨天下载的。它已正确安装。

我添加了一个存储库，现在当我输入sudo apt-get update它时会出现以下错误：

我已经阅读了很多问题，并一一尝试了所有问题。但它仍然导致问题。我检查了软件和更新中的所有选项，还尝试了不同的服务器。它导致了同样的问题

Answer 1

我从 Digital Ocean 网站上获取了这个：

Ubuntu 14.10（Utopic Unicorn）于 2015 年 7 月 23 日达到“生命终结”，不再受支持。Ubuntu 最近从他们的官方镜像中删除了它。如果您仍然需要 Apt 存储库，则需要编辑 /etc/apt/source.list 以指向：

http://old-releases.ubuntu.com/

我们还为它设置了一个镜像：

http://mirrors.digitalocean.com/ubuntu-old

尽管强烈建议您升级到更新的版本。14.10 中不再为任何软件包提供安全更新。我们正在提供该存储库，作为尚未升级到受支持版本的用户的便利和临时解决方法。

这对我有用。
