Dell Laptop with a recently installed Ubuntu 20.04.3 LTS with HWE-kernel.
Laptop has a Intell integrated GPU and an nVidia discrete GPU.

On install from Live USB, I said "yes" to install any proprietary drivers, which in turn created a MOK signature for SecureBoot.

But as far as I am aware, it is not using any nVidia proprietary drivers and used nouveau open source drivers, like this screenshot below ( which is NOT exactly the screenshot I had but just a look-alike as I can't run X11 at the moment, but I remember this is what I saw as I was contemplating on trying out the proprietary drivers ) :

Furthermore, I seem to recall that it was actually using the integrated Intel GPU for X11 instead of the discrete nVidia GPU. Now I don't have anymore proof of this, except that when I was doing things like lspci -vv, I was only seeing Intel as a "VGA compatible controller", etc. ... and hence, was contemplating on trying out the proprietary drivers.

After a few days using the laptop, when I was doing 'sudo apt-get update' and 'sudo apt-get upgrade', it did mention something about some changes were "kept back".

Next, installed mesa-utils from CLI via :

sudo apt-get install mesa-utils

/var/log/apt/history.log for today shows ( replaced by username with xxxxxx ):

Start-Date: 2022-01-26  09:11:02

Commandline: apt-get install mesa-utils

Requested-By: xxxxxx (1000)

Install: mesa-utils:amd64 (8.4.0-1build1)

End-Date: 2022-01-26  09:11:03

Then from GNOME Desktop, I ran "Software Updater", this icon :

When ran, it offered to do a "Partial Upgrade", which I then clicked on the button "Partial Upgrade" which is where things got broken after a reboot. On hindsight, I should have tried to figure out what the command line equivalents it was about to do, but too late. It also did remove packages that it says are no longer used ( mostly .386 packages )

Anyway, after a reboot, I do not get a GUI and I only have a terminal ( Ctrl-Alt-F1...F9 ). I don't even have wifi / networking enabled.

This question being posted here in the forum is being done on another laptop with the log files copied from problem laptop in question shown here.

I would hate having to re-install from Live USB, so I am asking if there is a way to "undo" what "Software Updater" / dpkg did ?

Looking around at what happened, I found these in /var/log/dpkg.log :
