Package system Is Broken 19.04 (Disco Dingo)

Question

I have a new installation, ran two commands in a terminal - sudo apt update - sudo apt upgrade Let it do it's thing. restored some data (that was a day I'll never get back) today I was tryng to install some programmes (VLC, Xine, Strawberry, K3b) they all failed to install from the Software Manager (including the snap catalogue) Then an orange dot appeared next to the Network Manager icon and whn I clicked on it to see what it was it said

I checked that I didn't install any 3rd party repos in my sleep - I didn't So ran the suggested command - no change. Rebooted - the dot telling me the system is broken remains

Googling suggested that I try to reconfigure dpkg with "sudo dpkg --configure -a"

this threw up a lot of activity in the terminal that finished with ---

So I started this project a week ago and here I am so close but it's still unusable

Apart from going through the agony of re-saving the data, a completely new installation, restoring my data and then (probably getting the exact same error) what can I do to start enjoying this exciting new Ubuntu experience ?
