Re: how to upgrade a debian system not connected to network

I have a two debian/unstable systems (let us name them PC-A and PC-B).
Both have got different packages installed. PC-A is connected to
internet with 2 MBps link and so there is no problem in upgrading it
regularly.
PC-B is not connected to internet. So I whenever I need to upgrade the
system I download the 5 CD's of sid form
ftp://ftp.fsn.hu/pub/CDROM-Images/debian-unofficial/sid/ ,
burn then in RW-CDs and then upgrade the system.
I want to know is there any method by which I can download the packages
requiring upgrade for the PC-B in PC-A (remember PC-A and PC-B have
different list of installed packages!)?
If I can do that, I can copy the .deb files to /var/cache/apt/archives
of PC-B via a portable usb-dsik and execute apt-get upgrade.
Right, as was said already if there is any way you can connect the
isolated computer to the internet connected computer, you could save
yourself a lot of hassle.
But if for whatever reason it must remain unconnected, then you'll want
to get the .deb packages downloaded on PC-A for transfer to PC-B.
apt-get has a -d option:
apt-get -d install [package] which downloads a .deb to
/var/cache/apt/archives/[package][version].deb
So to upgrade everything on PC-B:
1. Get a list of packages (to upgrade) on B, to A.
2. apt-get clean on A to clear current package cache.
3. Feed the list into "apt-get -d install [...]".
4. Burn .deb packages from apt cache onto CDs.
5. Don't forget the repository list files.
At that point I'll leave it. Really at 4 there you should figure out how
to create an apt repository cdrom (similar to the Debian installation
CDs). But I've never done that.
Perhaps the debian-cd package is you need for this.
