我刚刚安装了 Ubuntu 14.10 桌面版。我昨天下载了它。它已经正确安装。
我已经添加了一个存储库，现在当我输入时sudo apt-get update出现以下错误：

我读了很多问题，并逐一尝试了所有问题。但它仍然导致问题。我检查了所有选项软件和更新也尝试了不同的服务器。还是出现了同样的问题
答案1
我从 Digital Ocean 网站上获取了此信息：
Ubuntu 14.10 (Utopic Unicorn) 于 2015 年 7 月 23 日“终止使用”，不再受支持。Ubuntu 最近已将其从官方镜像中删除。如果您仍需要 Apt 存储库，则需要编辑 /etc/apt/source.list 以指向：
http://old-releases.ubuntu.com/
我们还在以下位置建立了镜像：
http://mirrors.digitalocean.com/ubuntu-old
尽管我们强烈建议您升级到较新的版本。14.10 中不再为任何软件包提供安全更新。我们提供该存储库是为了方便尚未升级到受支持版本的用户，并提供临时解决方法。
这对我有用。
答案2
我不确定|你的 ubuntu 服务器名称中间是否应该有一个管道字符……这不仅仅是错误消息的样子，是吗？
尝试检查您的软件存储库，也许尝试不同的镜像。此帮助页面应该有帮助https://help.ubuntu.com/community/Repositories/Ubuntu
我尝试连接到http://pk.archive.ubuntu.com它就挂了，也许它只是坏了。
答案3
您很可能位于物理/网络防火墙或其他网络安全设备的后面，其中 http/https 代理或一些网站类别被阻止，或者极少数情况下，端口 80/443/8080 已被预订
