我想安装Google-Earth,它需要ia32-libs。 所以,我做了apt-get install ia32-libs但错误弹出如下: 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 我该如何安装ia32-libs?
