Resumindo: exatamente a mesma pergunta que " Como executar o aplicativo de 32 bits no Ubuntu de 64 bits ", mas porque sua resposta não está mais funcionando.
Detalhes:
$ bios/extlinux/extlinux
bash: bios/extlinux/extlinux: No such file or directory
$ file bios/extlinux/extlinux
bios/extlinux/extlinux: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=6b439421a757a6f3a4218c726538be790a22ca13, stripped
$ uname -m

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial
Ou seja, no Ubuntu Xenial, a resposta de trabalho anterior não funciona mais:
$ sudo dpkg --add-architecture i386
$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libc6:i386 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:
libdb1-compat initscripts tzdata
E: Package 'libc6:i386' has no installation candidate
E: Unable to locate package libncurses5:i386
E: Unable to locate package libstdc++6:i386
E: Couldn't find any package by regex 'libstdc++6'
