You can save a lot of time using Jigdo to download Debian image especially when you have an old version of the image.
Mount the the old version of the image to a folder that you have access to, e.g.,
sudo mount debian-testing.iso /mntGo to Weekly Builds of Debian Testing Image to copy the link address of the jigdo file that you want to use. The first one is usually what you need.
Run the following command in terminal.
jigdo-lite link_to_jigdo_file
You will be asked about old vesions of images that you want to use to accelerate downloading. You can type in the path where you mounted the image. This process will be repeated until you don’t have any more old version of CD/DVD images to use. Just press enter to continue and files not found in the old versions of images will be fetched throught internet.
