最佳答案
几个月前我也遇到过类似的问题。我将存储库服务器从 lk.archive.ubuntu.com(ubuntu 默认安装)更改为 ubuntu 主服务器，即 archive.ubuntu.com。之后进行了“apt-get update”，一切顺利。
区域服务器有时会关闭。您也可以尝试从美国更改为主服务器。您可以通过手动编辑/etc/apt/sources.list 文件或从 ubuntu 软件中心单击按钮来执行此操作。
关于ubuntu - 无法在 ubuntu 12.04 中安装 g++，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/15846375/
