解决防火墙后 apt-get 更新中哈希总和不匹配的解决方法

Question

我在明显有防火墙的公司网络中使用 Ubuntu 12.04、64 位虚拟机。当我尝试运行 sudo apt-get update 或 sudo apt-get update --fix-missing 时，我收到此错误：

（假设在 _ubuntu 之前使用 archive.ubuntu.com）

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

我试过删除/var/lib/apt/lists其他帖子中提到的，但它不起作用。实际问题是公司防火墙破坏了下载流量，导致散列和不匹配。这是一个已知问题，如此处所示：

那么，是否有任何解决方法可以为我和公司防火墙后面的许多 Ubuntu 用户更新软件包？

Answer 1

我认为你的选择是：

1. 从另一个位置离线更新。请参阅如何在不使用 Synaptic 或 Keryx 的情况下离线更新 Ubuntu？

2. 与您的系统管理员交谈，让他们探索防火墙的解决方案。

Answer 2

如果上述解决方案不起作用，请尝试以下解决方案：

从文件夹中删除现有的受信任 GPG 密钥/etc/apt/trusted.gpg.d/

然后运行命令： sudo apt-key update

然后尝试运行：sudo apt-get update
