The ia32-libs package has not been available since Ubuntu introduced multiarch. The libraries mentioned in the message, lib32z1 lib32ncurses5 lib32bz2-1.0, will fully replace any functionality needed by ia32-libs. If a package specifically depends on the library, it will have to be repackaged.
意思就是这个库已经无效了，但是有很多个新的库完全可以替代这个库的功能
那就换吧
