Turn on 32-bit support for 64-bit Ubuntu

Open a terminal and type:

dpkg --print-architecture and
you will see something like this:

amd64
This means you have a 64-bit architecture kernel.

Step 2: Make sure you have multi-architecture support turned on

(Multi-arch support allows you to use 32-bit libraries if you have 64-bit libraries.)

Input:

dpkg --print-foreign-architectures The
output is:

i386
if you also There is no multi-arch support you need to turn it on.

Another second step: turn on multi-arch support.

Type:

sudo dpkg --add-architecture i386
sudo apt -get update
and it will start downloading the update and run.

After that you need to type:

sudo apt-get dist-upgrade
