How to download all dependencies and packages to directory

Question

The marked answer has the problem that the available packages on the machine that is doing the downloads might be different from the target machine, and thus the package set might be incomplete.

To avoid this and get all dependencies, use the following:

apt-get download $(apt-rdepends <package>|grep -v "^ ")

Some packages returned from apt-rdepends don't exist with the exact name for apt-get download to download (for example, libc-dev). In those cases, filter out those exact names (be sure to use ^<NAME>$ so that other related names, for example libc-dev-bin, that do exist are not skipped).

apt-get download $(apt-rdepends <package>|grep -v "^ " |grep -v "^libc-dev$")

Once downloaded, you can move the .deb files to a machine without Internet and install them:

sudo dpkg -i *.deb

Same question already answered here: How to list/download the recursive dependencies of a debian package?

try:

PACKAGES="wget unzip"
apt-get download $(apt-cache depends --recurse --no-recommends --no-suggests \
  --no-conflicts --no-breaks --no-replaces --no-enhances \
  --no-pre-depends ${PACKAGES} | grep "^\w")

# aptitude clean
# aptitude --download-only install <your_package_here>
# cp /var/cache/apt/archives/*.deb <your_directory_here>

The aptitude --download-only ... approach only works if you have a debian distro with internet connection in your hands.

If you don't, I think it is better to run the following script on the disconnected debian machine:

apt-get --print-uris --yes install <my_package_name> | grep ^\' | cut -d\' -f2 >downloads.list

move the downloads.list file into a connected linux (or non linux) machine, and run:

wget --input-file myurilist

this downloads all your files into the current directory.After that you can copy them on an USB key and install in your disconnected debian machine.

This will download all the Debs to the current directory, and will NOT fail if It can't find a candidate.

Also does NOT require sudo to run sript!

nano getdebs.sh && chmod +x getdebs.sh && ./getdebs.sh

#!/bin/bash

package=ssmtp

apt-cache depends "$package" | grep Depends: >> deb.list

sed -i -e 's/[<>|:]//g' deb.list

sed -i -e 's/Depends//g' deb.list

sed -i -e 's/ //g' deb.list

filename="deb.list"

while read -r line
do
    name="$line"
    apt-get download "$name"
done < "$filename"

apt-get download "$package"

Note: I used this as my example because I was actually trying to DL the Deps for SSMTP and it failed on debconf-2.0, but this script got me what I need!

Somewhat simplified (and what worked for me) way that worked for me (based on all the above)
Note that dependencies hierarchy can go deeper then one level

Get dependencies of your package

$ apt-cache depends mongodb | grep Depends:
  Depends: mongodb-dev
  Depends: mongodb-server

Get urls:

sudo apt-get --print-uris --yes -d --reinstall install mongodb-org mongodb-org-server mongodb-org-shell mongodb-org-tools | grep "http://" |  awk '{print$1}' | xargs -I'{}' echo {} | tee files.list
wget --input-file files.list
