How to remove Broken Installation

Trying to install unifi on a i386 pc and cannot, its not supported. Now I just want to remove this broken install and move on. How can I do that? TIA

Here are error messages from ubuntu terminal:
N: Skipping acquire of configured file 'ubiquiti/binary-i386/Packages' as repository 'https://www.ui.com/downloads/unifi/debian stable InRelease' doesn't support architecture 'i386'

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libssl1.1 : Breaks: libssl1.1:i386 (!= 1.1.1f-1ubuntu2) but 1.1.1f-1ubuntu2.21 is installed
libssl1.1:i386 : Breaks: libssl1.1 (!= 1.1.1f-1ubuntu2.21) but 1.1.1f-1ubuntu2 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
NOTE:
the "--fix-broken install" did not work either

udo apt --fix-broken install

I presume you know that there are no supported Ubuntu versions now for i386 (32bit) hardware?

Give us more information of the current hardware and software you're using with the output of inxi Fzx using code tags please for that pasted output.
See my signature below for a Code-tags how-to.

sorry sudo apt update is broken.
output lscpu and inxi is below, not sure if the code is tagged or not. An ubuntu beginner
