Attaching screenshots to Launchpad questions does not work. If you see the need to show a picture, then you have to make that picture available on the internet (e.g. by uploading it to some public image hosting service like imgur)

To your problem:

For diagnsotic purposes, what output do you receive for the following commands (to be executed in a terminal window, and the output transferred to this question document by copy and paste):

uname -a
lsb_release -crid
sudo dpkg --audit
sudo dpkg --configure -a
sudo apt update
apt policy glib-networking: libgnutls30 glib-networking-services glib-networking-common

Strange. Your output is somewhat incomplete. There are no available versions listed for the glib-networking packages.

This looks completely normal.

I recommend that you try completely re-loading the package inventory lists and then try again.
If that still produces the same output, then you probably should try switching to a different repository server and try again.

sudo rm -v /var/lib/apt/lists/*mirror.lstn.net*
sudo apt update
apt policy glib-networking: libgnutls30 glib-networking-services glib-networking-common

after your suggested answer update loaded a lot more packages but still
did not complete would not let me change into settings to change sources
on reboot locks up at login I get a black screen no courser no response
to the keyboard.

When you boot your system, can you bring up the grub menu (by hitting the left shift or escape keys early during boot)?

If you can do that, select "advanced mode" and "root command prompt".
Does that work?

If yes, issue the command

sudo mount -o remount,rw /
sudo dpkg --configue -a

What is the gist of the output that you receive (especially the last lines)

(you can shutdown from that mode by "sudo poweroff").

Sorry it has taken so long to respond.  I have made several attempts
with no success the most I get is a blinking cursor on a black screen
and no keyboard response.

You have to find the right timing.
Try again, hitting the left shit key several times, starting very early in the boot process.

after several attempts I still end up at the same blinking cursor
however I get the flash of a line of text before the cursor I get the
same thing whether I shift key repeatedly , hold it down ,or do nothing.
I will keep trying but that is the result so far

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

after many attempts the most I get is a blinking cursor and a black
screen and no keyboard response at all. Is all I can do is reformat the
partition and re install ?

You need the grub menu.
If you get a blinking cursor, then you have already missed the moment where you have to press the left shift key.

(another possibility is booting an installer in the "try Ubuntu without installing" mode and then trying to re-install the kernel to your disk partition)

It will probably be Monday before I get access to that computer again
(traveling for the holidays) which CD would be the better choice I have
both 20.04 and 22.04 available.

Usually the advice is using the installer with the release that's installed on the disk, but any version should work.

I have tried both suggested methods several times with no success  with
the installer either I get the live CD or it wants to wipe the partition
and reinstall fresh. I have tried this with both 20.04 and 22.04 with
the same results. I have a new SSD arrived late yesterday I will move
this SSD to an external enclosure  where I can recover every thing
except the settings for 20.04 that failed the upgrade to 22.04

"the installer either I get the live CD or it wants to wipe the partition"

Yes, that's the starting point.

You have to boot the installer in live mode ("Try Ubuntu without installing") and then change-root into the installation on the hard disk,

See https://help.ubuntu.com/community/LiveCdRecovery#Update_Failure but note, that your root partition may be named differently (not /dev/sda1).
