jdk 和　eclipse 都已经搞好！但是由于下面这个问题卡住了！

cky@ckypc:/var/www/1.Web$ sudo apt-get install ia32-libs

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