ubuntu安装ia32-libs出现问题

ubuntu 14.04安装ia32-libs使用命令

sudo apt-get install ia32-libs

出现如下错误：
Reading package lists... Done

Building dependency tree       

Reading state information... Done

Package ia32-libs is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

However the following packages replace it:

  lib32z1 lib32ncurses5 lib32bz2-1.0

E: Package 'ia32-libs' has no installation candidate

只要运行提示的3个库即可：

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
