我刚刚安装了Ubuntu 13.10（Saucy），但是我尝试通过sudo apt-get install安装任何东西都失败了，并且会抛出一系列404错误。
例如 - 安装tmux
[jeeves@HAL] hadoop > sudo apt-get install tmux
[sudo] password for jeeves:

Err http://us.archive.ubuntu.com/ubuntu/ saucy/main tmux amd64 1.8-4
404 Not Found [IP: 91.189.91.23 80]
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/t/tmux/tmux_1.8-4_amd64.deb 404 Not Found [IP: 91.189.91.23 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
在这种情况下，它无法获取存档网址。
安装
mysql-server时，我遇到了类似的问题。....
Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/m/mysql-5.5/mysql-common_5.5.37-0ubuntu0.13.10.1_all.deb 404 Not Found [IP: 91.189.91.23 80]

....
...和许多其他包。
我甚至尝试了sudo apt-get update并运行--fix-missing？
是Ubuntu存储库暂时关闭了（考虑到有多少人依赖它，这似乎很奇怪），还是我错过了什么？
编辑：当我尝试sudo apt-get update时，会出现以下情况。更新本身无法工作，因为找不到资源。
