Hi Dave,
Concerning Option B.
Use the "Add Shapefile" menu, not "New Shapefile" menu.
The former one adds an existing shapefile to your QGIS project. The
later one creates a new empty file (and hence asks you if you want to
overwrite the existing one with data).
Best regards
Matthias

With a clean install of Ubuntu-20.04, I downloaded qgis from the
Ubuntu repository.
This is qgis-3.10.4-A . During the installation I was asked if I
wanted my old settings preserved, I said No.
I get different results depending on how I proceed.
A. If I open the application and choose the blank project, add New
Shapefile Layer and navigate to "DCDB.shp" I get "The layer already
exists, overwrite ?" (which seems wrong for a blank project), answer
Cancel. The input file DCDB.shp is written to a file size of 100 bytes
from 9.8 MB. This is exactly the same as the problem I was having
before, which I eventually gave up on.
B. If I don't open qgis, but simply double-click on "DCDB.shp", it
opens qgis and loads the layer, which renders correctly. I can change
the polygons' colours based on the TENURE field. I can save the
project and close, but on reopening qgis, my project is not presented.
If I navigate to the newly created ./gis/Lot11.qgz it opens as a blank
project with no layers.
At qgis.org I see that you released qgis-3.12 on 17 April 2020, less
than a week before Ubuntu-20.04 was due to be released.
At https://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu ,
I cannot understand what you mean by "To have newer versions, you have
to add alternative software repositories, by adding one of the
deb-lines below to your /etc/apt/sources.list file." There are no deb
lines below. There are 15 URLs.
Please help.
Dave
