Have you considered using apt-offline? apt-cache show apt-offline apt-offline is an Offline APT Package Manager. apt-offline can fully update and upgrade an APT based distribution without connecting to the network, all of it transparent to APT. apt-offline can be used to generate a signature on a machine (with no network). This signature contains all download information required for the APT database system. This signature file can be used on another machine connected to the internet (which need not be a Debian box and can even be running windows) to download the updates. The downloaded data will contain all updates in a format understood by APT and this data can be used by apt-offline to update the non-networked machine. apt-offline can also fetch bug reports and make them available offline. It would take some sneakernet trips back and forth with a portable storage medium such as a USB storage device or some such but that would be a possibility. Can get security updates and so forth that way. > torrents, where as jigdo has available 13 DVD images: > > http://cdimage.debian.org/debian-cd/8.1.0/amd64/bt-dvd/ > > http://cdimage.debian.org/debian-cd/8.1.0/amd64/jigdo-dvd/ Yes. All of the DVDs images are available. It is only that Debvian is not hosting them as iso images on their download site. It is a problem of mirror site disk space and bandwidth. Mirror sites do not have infinite disk space nor infinite bandwidth. There is a cost to everything. At some point there isn't enough space nor bandwidth nor the associated actual cost of hosting them. Mirrors would stop hosting Debian if it grew without bounds. Therefore compromises must be made. The very little used images are not hosted. It is very unusual for anyone to need or to use those images. However they are available and you can create them for yourself very easily. If you desire any or all of the 13 DVD set for amd64 then they are available for very easy creation using jigdo-lite. Here is an example. # apt-get install jigdo-file $ mkdir jigdo-stuff $ cd jigdo-stuff $ jigdo-lite --noask http://cdimage.debian.org/debian-cd/8.1.0/amd64/jigdo-dvd/debian-8.1.0-amd64-DVD-1.jigdo ...lots of output and some minutes of time... OK: Checksums match, image is good! real 24m14.239s user 1m23.772s sys 1m9.412s $ ls -ldog -rw-rw-r-- 1 3994091520 Jun 14 12:38 debian-8.1.0-amd64-DVD-1.iso -rw-rw-r-- 1 3.8G Jun 14 12:38 debian-8.1.0-amd64-DVD-1.iso That took me 24 minutes using a fast local mirror on GigE. Pulling 3.8 Gig off a slower WAN would take considerably longer. > My friend keeps the DVD image torrent (in Deluge) on his computer when he > sleeps and it is downloaded by morning.

But I can not find more than 3 DVD images on torrent. > What can I do ? I don't know of any other way than to run jigdo to build the DVD image. Therefore your friend would need to be able to run it on their computer or you would need to to be able to leave a portable machine such as a laptop with enough disk space. I don't know if there is a way to run jigdo on a Windows machine for example. Temporarily leaving a laptop there would allow you to have control over the download. Note that the entirety of the disk space is pretty large. 4G times 13 DVD images is 50 plus Gig of data to download. If I were heading to an Antartic station where access to the Internet is a precious thing I would definitely download the entire set. If I were using sneakernet to get data across town I would probably try apt-offline and see if it could be used to download just what was needed. Good luck! Bob
