Save update installers with apt-offline

This may be of use to those who are setting up many computers with Zorin-OS, or who may be setting up computers with little or no network access.

If you are installing Zorin-OS on a computer that has limited network access, and the 400 MB of updates are a burden to download, you can use apt-offline to generate a signature file with a list of the desired updates. This file can be taken to a networked computer running Ubuntu and apt-offline, and the update install files can be downloaded there. These files can then be carried back to the un-connected computer and installed.

I was helping several people set up Zorin-OS, and they told me that the updates would take too long for them to download, so I downloaded them once, and then let them copy the .deb files to USB drives to take home.

This page describes the process

Also, I wrote a description at http://ce107.pbworks.com/w/page/86570113/OfflineUpdates

that way, would be easier than try to use the AptOnCd software.
- which does the same thing, - but can have issues.
