Assuming that I have a server with Ubuntu server newly installed on it. I was thinking of installing the very same version on
Virtual Box (Or any other virtualization software), connect it to the internet and use
apt-get to only download the packages for upgrading the system and the new software such as (
openjdk6-default-headless..etc). Then copy the downloaded packages from the archive folder to the offline server's archive folder through a USB stick.
So now the virtual system won't actually be upgraded nor have any new software installed. But would running the very same
apt-get commands on the offline system without the download directive
-d be executed without issues ?
*EDIT:*This needs to be as simple as possible because I'll have to write a guide for our client to do this on his own and so it won't be acceptable to require deep Linux knowledge to do this.
