Back when 12.10 was released, the Alternative CDs were dropped. Without those it seems that is is not possible to upgrade from one version of Kubuntu to a newer version unless you have a direct internet connection. I have patchy and expensive internet, and would very much like to be able to download a whole chunk of stuff, copy it over to my Kubuntu box, and do an "offline" distribution upgrade.

Can anyone tell me if this is possible?

Can apt-offline be used to do distribution upgrades?

Can Keryx be used to do this somehow?

Oh, another complication: the machine I have that has occasional but great internet connection is a Windows box, so it'd be great if there is a way to download a whole chunk of stuff using this Windows box.

I realise that I'll probably have to do several distribution upgrades (i.e. from 12.04 to 12.10, then 12.10 to 13.04, then 13.04 to 13.10), I'm OK with that.
