Keryx: Offline Package Installation

from OMG! UBUNTU! by

The Keryx Project allows users with limited internet connectivity the ability to download and update packages for Ubuntu.

The real beauty of Keryx is that access to a Linux computer is not required to access and download updates as the application runs from a USB drive and works with Linux, OS X and, perhaps most vitally in many situations where internet access it limited, Windows.


How it works

To use Keryx you first have to create and save a “project” to your USB drive. This is simply a snapshot of your currently installed packages on Ubuntu computer.

Then, when somewhere with internet access, you plug in your USB key, load up your profile and click the ‘Get Updates’ button to download all available updates to your USB drive for installation back at home.

By being able to reference your systems’ package list – just as Synaptic/APT do – Keryx download anything you don’t need but does ensure all necessary dependencies are pulled in.

How do I get new applications?

Use the search bar to locate the application you want to install. Highlight it, right click on it  and then choose’ Download’.

The package(s) will be downloaded to your device ready for installation back on your ‘buntu box.

Installing downloaded updates/applications

When back at home/your computer you just plug your USB drive in, load up Keryx and use the ‘Project > Install’ button to install and apply downloaded packages.

The project has been in development for the last 3 years and the work so far is fantastic – but the team have plenty more ideas and features they would like to implement but not as much time or manpower to do it.

If you’d like to help lend a hand to such a worthwhile project head over and learn how you can get involved.


  1. Hello,

    I'm the editor of OMG! Ubuntu! (and the author of this article) and as per our copyright policy you need to stop 'importing' posts from our feed.

    I must say, as of now you have the best blog on Ubuntu. Your way of presentation is awesome.

    As for as importing is concerned, I used to maintain this blog some time ago (read years ago), but of late due to lack of time, I no longer update it myself. I rather 'import' articles around the web, which I like or feel would come in handy over the time (as opposed to bookmarking them).
    That is one of the reasons why I never forget to copy "from OMG! UBUNTU! by".

    But if it your policy, I guess I won't 'import' any more posts from OMGUbuntu.
