The problem is that the .iso is not a mounted filesystem.

You could:

$ mkdir /home/richard/dvdmount
$ sudo mount /home/richard/dvd.iso /home/richard/dvdmount

If it complains about the filetype, try -t udf or -t iso9660.

and then you can use this sources.list line:

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

(or similar; I don't recall if the debian repository on disc
starts in the root of the disc)
