@cfi, @Lukas, thank you both, that was the direction I needed.
Maintenance -> Feed -> Upgrade
I had somehow not found that option after spending ages looking through the options.
And then go to:
Advanced ->Support -> Shell: journalctl -f
This was a great help!
It took several long hours on a fast internet connection before the feed was complete and the interface showed what I expected to see.
Thank you both. 
Now I’ll have a play with it and create a few scans.
