I am getting bored with soliloquy and waiting for self-education to bear
fruit.

The starting point is

 > deb file:///home/richard/dvdmount stretch main contrib trusted=yes

As the sources.list manual indicates, this should be

 deb [trusted=yes] file:///home/richard/dvdmount stretch main contrib

and will get the error message

 > Release file for file:///home/richard/dvdmount/Release is expired (invalid since...).

As sources.list(5) relates:

We now update the line to

 deb [trusted=yes check-valid-until=no] file:///home/richard/dvdmount stretch main contrib

and there we have it. Success.
