How do I install 32-bit apps on Ubuntu 20.04 64-bit instead of 64-bit apps? I am using AMD Ryzen system with 16 GB ram and GT210 GPU

Asked by gesgersghsehs

If I install 'Firefox' for example it installs the 64-bit version but I want to install the 32-bit version instead. How do I do it?
I know there is the tarball folder like '' but this is just one and its a simple folder that doesn't update at all?

How can I fix this issue?

Ubuntu doesn't support 32bits any more. You would need to build a LOT of 32bit stuff to run it.

Why 32bit Firefox? What is the usecase here please?

Firefox was an example!

Can Ubuntu still run 32 bit apps?

actionparsnip's comment is not fully complete. tells that 32bit versions are built for a limited list of packages (mainly _libraries_) to allow some legacy packages to be installed.
The list of the libraries can be found in

What you need for that to work is adding i386 as foreign architecture to the dpkg settings (see manpage for dpkg).

If you find a 32bit application that depends only on shared libraries that are provided in Ubuntu's i386 packages, then this should work. Please note that Ubuntu does not provide 32bit _applications_ any more (in Ubuntu 19.10 and later).

Still the question is: What do you expect to gain from installing the 32bit version of a program instead of the 64bit version?

Can you help with this problem?
