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:
lib32ncurses5 lib32z1
E: Package 'ia32-libs' has no installation candidate
解决方法：
sudo apt-get install lib32z1 lib32ncurses5
sudo apt-get install lib32stdc++6
去掉ia32-libs，重新更新系统：
sudo apt-get update && sudo apt-get install -y bzip2 build-essential libc6-dev-i386 lib32z1-dev libncurses5 libncurses5-dev u-boot-tools vim squashfs-tools gettext git zip subversion bc
