Create & maintain local Kubuntu repository
I am new to this forum so apologies in advance if this is posted in the wrong place.
At my workplace, we have 2 servers running Debian 6 and have another 8 machines running Kubuntu, mostly 11.10 and about to upgrade to 12.04 LTS. Most are 64 bit machines but one is a 32 bit machine (it is infrequently used to control a scientific instrument, and is overdue for an upgrade).
What I would like to be able to do is to setup a local repository for Kubuntu and upgrade all the Kbuntu machines from that. I have installed apt-mirror and started playing with that. However I am still quite new to Linux and am not confident of getting it right.
Is there any how-to here at HowtoForge on just how to achieve the setup of a local repository on one of our machines, not necessarily using apt-mirror; perhaps there is some other suitable tool, and then reconfiguring all the other computers to us that local repository?
Is it possible for the repository to include both the i-386 and amd64 architecture files or do I need two separate repositories for that? If the latter, how then do I use them both? I am guessing a more comprehensive sources.list file would do the trick.
Also is it possible for a local repository to be only a subset of the full distro based on the software we use here or does it have to be the full distro? If so, how do I restrict the repository to just the subset I want?
Thanks in advance to those more knowledgeable than me. Any advice is very welcome.
