Failed to install nvidia drivers - apt --fix-broken install not working

I have tried installing drivers for my GeForce 840M graphics card.
I tried running:

sudo ubuntu-drivers autoinstall

. It worked until I got this:

The following packages have unmet dependencies:
 libnvidia-ifr1-430 : Depends: libnvidia-gl-430 but it is not installed
 libnvidia-ifr1-430:i386 : Depends: libnvidia-gl-430:i386 but it is not installed
 nvidia-driver-430 : Depends: libnvidia-gl-430 (= 430.09-0ubuntu0~gpu19.04.1) but it is not installed
                     Recommends: nvidia-settings but it is not installed
                     Recommends: nvidia-prime (>= 0.8) but it is not installed
                     Recommends: libnvidia-gl-430:i386 (= 430.09-0ubuntu0~gpu19.04.1)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I tried running

sudo apt --fix-broken install

and got this error:

It looks like I am stuck in this loop…

Since you already reinstalled, code 43 means your gpu is broken. Sorry.
