最近我在旧机器上安装了旧版本的 Ubuntu。每当我尝试安装任何软件时，都会收到一条错误消息，说找不到它：

$ sudo apt-get install vlc
Reading package lists... Done               
Building dependency tree       
Reading state information... Done    
E: Couldn't find package vlc

尝试在 ubuntu 服务器 10.04 LTS 实例上安装 Samba 时出现以下错误：

无法获取 http://us.archive.ubuntu.com/ubuntu/pool/main/s/samba/libwbclient0_3.4.7~dfsg-1ubuntu3.6_i386.deb 404 Not Found [IP: 91.189.88.31 80]

有什么办法可以解决这个问题，这样我就不必等待更新服务器恢复了吗？我将来如何防止这种情况？

编辑：我在 askubuntu 上发现了一个非常相似的帖子：无法获取 http://in.archive.ubuntu.com/ubuntu/dists/maverick/Release

但是 Lekensteyn 的回答不起作用（尽管它帮助了给定问题的作者）......我仍然得到以下信息（在将 repo 切换到 in.archive.ubuntu.com 之后）：
