联通的緩存劫持会导致 APT 和 YUM 更新软件源时校验失败

[raysonx]

看到有人给这种劫持洗地，忍不住来发一帖。 比如用 APT 更新软件源时，联通的缓存会导致校验失败：

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

不明真相的新手用户肯定会因为这种问题受阻。

聯通的有緩存 電信的可能只是反代
不過這個 iptables 應該能幹掉吧..
話說聯通直接用首都在線的 mirror 就好 速度挺快的

[aihimmel]

SSL

[dangge]

安利一波
https://mirrors.zzu.edu.cn/
带宽不大,但是好歹有 SSL 保证不被劫持
PS:其实 USTC 啊 TUNA 这些大学的镜像站也是有 SSL 的~

[zstack]

用阿里云的 mirror 应该速度质量都比较有保障

[Cu635]

解决方法是用 https 链接源，这时候需要安装 apt-transport-https 这个包。

联通的还算好，那些小运营商的缓存那更可恶。

http://archive.ubuntu.com
http://ppa.launchpad.net
apt-get update 时总是 Hash Sum Mismatch ，搞了 2 天，一直没法安装软件。今天才发现 TMD 联通搞鬼。 archive.ubuntu.com 有镜像还好点， ppa 没有镜像。日了狗的联通。

帝都实测，昨天还没有今天就被劫持了 日了 U •ェ•*U 服了。。。

真怀疑 到底有没有底线。
