Ubuntu package offline install

apt-get

Use apt-get with the "--print-uris" option to do it. I also add "-qq" so it would be quiet.

Create script:

sudo apt-get <<>> --print-uris -qq | sed -n "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/wget -c 1/p" > script.cmd

Examples

sudo apt-get install anjuta --print-uris -qq | sed -n "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/wget -c 1/p" > install-anjuta.cmd
sudo apt-get upgrade --print-uris -qq | sed -n "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/wget -c 1/p" > upgrade.cmd
sudo apt-get dist-upgrade --print-uris -qq | sed -n "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/wget -c 1/p" > dist-upgrade.cmd

Create md5sum file:

sudo apt-get <<>> --print-uris -qq | sed -n -e "s/[0-9]%[0-9a-f][0-9a-f]//" -e "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/4 ./2/p" > md5sum.txt

Examples:

sudo apt-get install anjuta --print-uris -qq | sed -n -e "s/[0-9]%[0-9a-f][0-9a-f]//" -e "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/4 ./2/p" > md5sum.txt
sudo apt-get upgrade --print-uris -qq | sed -n -e "s/[0-9]%[0-9a-f][0-9a-f]//" -e "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/4 ./2/p" > md5sum.txt
sudo apt-get dist-upgrade --print-uris -qq | sed -n -e "s/[0-9]%[0-9a-f][0-9a-f]//" -e "s/'([^ ]+)' ([^ ]+) ([^ ]+) MD5Sum:([^ ]+)/4 ./2/p" > md5sum.txt

Create script to download repository listings:

sudo apt-get update --print-uris -qq | sed -n "s/'([^ ]+)' ([^ ]+) ([^ ]+) :/wget -c 1 -O 2.bz2/p" > update.cmd

Synaptic

In synaptic you can select the packages you want to install and under the first menu there is an option to generate a script which you can take to another machine and run there. This script will "wget" (i.e. "download") all the packages you specified that you wanted (and their dependencies) which you run on a computer that does have internet access.

Once run you'll have all the package files needed by the disconnected computer. Carry them on a CD/USB stick and install them by sudo dpkg -i *.deb.

Cube

You can use Cube. It is an offline package management system which is compatible with Ubuntu, Linux Mint and other distributions that use apt-get.
