How can I install software or packages without Internet (offline)?

I have upgraded Ubuntu 11.10 (amd64) to 12.04 (amd64) on one of the laptops I have, I have another laptop which is also running 11.10 (amd64) I want to use the packages downloaded on the first laptop on the second laptop so that both have Ubuntu 12.04 I checked on first laptop (now running 12.04 ) downloaded upgrades are residing in /var/cache/apt/archives
I have done an sftp for those packages from laptop 1 to laptop 2.

On the laptop 2 I have tried putting those package files into /var/apt/cache/archives
and then just firing the upgrade process do-release-upgrade, and unfortunately this does not work and rather than picking the packages from
/var/cache/apt/archives

it goes to some thing like 

http://us.archive.ubuntu.com/ubuntu/ precise/main qemu-utils amd64 1.0+noroms-0ubuntu13 [353 kB]

and so on and is downloading things,

Now what I want to know is how do I make sure do-release-upgrade uses these in my laptop and does not downloads 700 mb of updates because this will take 8-10 hours at my end so I want to utilize the upgrades which were downloaded during the upgrade process on one of the systems. If there is a way in this situation let me know.

I love this trick. It should work fine. Perhaps the files are owned by the wrong user. What I do is first install an ssh server on the machine with updates. sudo apt-get install openssh-server

The copy them into place from the other machine:

cd /var/cache/apt/archives
sudo scp <user>@<machine with updates>:/var/cache/apt/archives/* .

The dot tells scp to put them in the current directory.

  • No this does not work I already did that and inspite of having them done an scp to current machines /var/cache/apt/archives it will still connect to internet to download the packages the presence of packages in /var/cache/apt/archives had no difference at all

  • Maybe there is something about the user or permissions of those files. With the sudo as I did it worked fine for me, they were not downloaded again and were installed correctly. Not sure what is different from your configuration compared to the ones I have done successfully.
