    HOWTO : Script for using apt offline

    Hi,

    Tired for waiting my internet connection, and as many people ask for how to do it, I wrote a little script to allow the use of apt-get offline. The main advantage in comparison to the real apt-offline tool (which I didn't try ) is that it doesn't need to have apt on the connected computer (ie you can download packages from a rpm-based distribution, for instance).

    Here it is, just copy this code in your favorite text editor, save it as apt-off on your usb flash/hard drive (or any other kind of mobile disk) and make it executable by typing chmod +x apt-off in a terminal.

    Code:

    All the instructions are explained by apt-off -h. Enjoy !

    PS : Please report any problems (such as English corrections... ).

    Edit : I forgot to say that I inspired myself from this page.

    Please note that the French version (see here) can be much more up-to-date (update of this (english) version has been done today, 12/22/06).
