Though in most North American cities one cannot find a spot without at least a weak WiFi signal, many of us Linux geeks still live in rural areas with less Internet connectivity. Also, in various non-Westernized nations, there is a growing number of Linux users who may have a computer at home, but cannot afford a decent connection. For both groups, software updates typically demand an Internet connection, which can make updating difficult if not impossible. There is now a solution though, a new program called Keryx.
Keryx was written by Southern Illinois University computer science student Chris Oliver, who wanted a way to download software and updates for Ubuntu systems that had little or no connectivity. Simply put Keryx on your pen drive, use it to create a new project file which retains a copy of your software sources and other system details, then take the pen drive to a computer with a better connection. Via it’s Synaptic like interface, users can then select all updates for download, plus select any other software they may want to install, complete with dependency resolution.
