Progress report...
------------------
So the endeavour above did not work at all...
No way I could get out of the situation where it cannot find a bootable
operating system....

So I decided to start over and let Ubuntu do it all instead of me trying to
partition in a custom way.

I had big problems in actually loading the live dvd again, it seems like the PC
had totally switched to no-cooperate mode...

But after a few hours I finally managed to get to the Live CD again.
This time I let it do the disk handling itself after selecting "Erase disk and
install Ubuntu". It turns out that after all is done it has used all of the 500
GB disk as one system partition containing everything, except for a small FAT
partition at the start of the disk. And the big one is not a primary partition
it seems to be an extended partition which houses the main partition inside.

So now I have to shrink the main partition and create a new home partition and
then manage to switch over from the single-partition setup to the
home-on-separate-partition I wanted to get to.

Of course I cannot do the re-partitioning while it is mounted on the running
system, so I need to be able to boot to my GParted ISO.
And luckily now for some reason it is possible to boot off a USB stick instead
of DVD. Don't ask me why, maybe because the main SSH disk is better now?

Anyway the shrink and creation of a home partition worked, but it is not yet set
up to use this new home.

Also it turned out that the DVD I had for 20.04 LTS was the stock version and
*not* Cinnamon as I had wanted. With Focal Fossa it seems like I cannot set the
desktop background to a single solid color, it requests it to be a "picture",
which I do not like at all.

Is there some trick to set a solid color background on this version of Ubuntu?

Or do I have to install a second desktop manager for this? And will that also
duplicate all of the applications???

Or repeat all of this once more using a recent Cinnamon DVD?
