一位在大洋洲地区旅行的用户递给我一台笔记本电脑，我试图运行该命令，apt-get update但返回了以下消息

我直接连接到互联网运行该命令，没有通过任何代理。当我尝试访问该 URL 时，我收到“禁止访问”错误。几天前我对此没有问题。我能够解决该问题的唯一方法是将 URL 更改为http://nz.archive.ubuntu.com/ubuntu/ precise main restricted文件http://archive.ubuntu.com/ubuntu/ precise main restricted中的URL sources.list。
为什么我会突然收到这样的错误？
该笔记本电脑运行的是 Ubuntu 12.04 LTS
答案1
您收到此错误是因为服务器。该服务器发生了一些变化，现在它仅提供“packages”文件作为“packages.gz”和“packages.bz2”。这完全不是您的错。
但是，我建议恢复到其他国家的服务器，而不是主 archive.ubuntu.com，因为它受到限制，无法体验全速。
答案2
是的，nz.archive.ubuntu.com由于某种原因返回了 403 Forbidden。也许他们的服务器配置有误。也许您处于黑名单子网中。尝试在浏览器中打开该 URL。您也可以联系此镜像站点的所有者来报告此问题。您可以使用另一个镜像。Ubuntu 上有很多这样的镜像。
