How about writing an entry in /etc/apt/sources.list for the mount point of your USB drive ? deb file:...path... buster main I understand that the path after "file:" should point to the directory with subdirectories ./dist and ./pool . That would be the root directory of the mounted ISO on the stick. Assumed that the USB drive is mounted at /mnt/iso i'd try: deb file:/mnt/iso buster main If all works well, the request for DVD-1 should not appear any more. A package from a DVD with higher number will pose the problem again. In this case i would advise one of the ISOs "STICK16GB-1", "BD-1", "DLBD-1" depending on how much the USB drive can take. Have a nice day :) Thomas
