The following packages have unmet dependencies:
 ia32-libs : Depends: ia32-libs-i386 but it is not installable
E: Unable to correct problems, you have held broken packages.

saya menggunakan

# uname -a
Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux

Sumber saya. Pertama adalah

# cat /etc/apt/sources.list

Karena Wheezy memperkenalkan multiarch, ia32-libspaket tersebut sekarang sudah tidak digunakan lagi. Sekarang dimungkinkan untuk menginstal paket 32bit secara langsung:

dpkg --add-architecture i386 # enable multi-arch
apt-get update
apt-get install libc6:i386 # install base 32bit libraries
