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) -dsr-
