Now that that has been sorted out we can move on with some educational
problem solving. You have used the sources.list entry:

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

This line is incorrect; the format for an entry is in sources.list(5).
You then replaced this entry with another one that was also incorrect,
getting the error message

  The repository 'file:/home/richard/dvdmount stretch Release' is not signed.

I suggest you devise a valid entry and post it here. After 'apt update'
you will get a different error message that will enable you to progress
to a solution.
