Not sure what you mean by install it individually. You just install
apt-cacher-ng `apt-get install apt-cacher-ng` on a single machine, and
on each of the client machines you just create a file named 01proxy in
/etc/apt/apt.conf.d having
Acquire::http { Proxy http://xx.xx.xx.xx:3142;; };
where xx.xx.xx.xx is the IP of the machine on which apt-cacher-ng is
installed. That's all. You can also do the same on the apt-cacher-ng
machine also.
On each client machine then run `apt-get update` and you're done. It
doesn't matter it's 32bit or 64bit. Of course the firewall should be
opened on apt-cacher-ng machine for tcp port 3142.
Did you see any message mentioning 32bit and 64bit there?
Like in Windows, WSUS caches the packages for almost all Windows product
updates, doesn't matter if it's 32 or 64 bit, doesn't even matter if
updates are for XP or Vista or Win7.
So, all I'm asking if it's possible to achieve same kind of
functionality in Ubuntu too?
Yes, these caching servers do just that. Irrespective of the
architecture or even the distribution version (atleast Ubuntu/Debian
based).
Or do you want to have a complete ubuntu mirror on your machine? I don't
think that would be a good idea.
[1]http://www.ubuntugeek.com/apt-cacher-ng-http-download-proxy-for-software-packages.html
It's too complicated a setup in the link above. Also, the writer is
importing packages from /var/cache/apt/archives to prevent downloading
them again - this is just for the first time. You may not need it at all.

[ilugd] Distributed updates in Ubuntu
Please, bear with me, if I'm not able to properly present my requirement. There are some 32 and 64 bit ubuntu systems in same network. I want only one system(like, one 32 and one 64 bit systems) to be updated and upgraded on daily basis. And, rest of the systems, to fetch those updated packages before they go online and check for new packages. There is some vague idea in my mind to achieve this. Check the 'master' systems /var/cache/apt/archives directory, list all deb packages and install them accordingly. Make one entry in source.list of each system to do the same. But, I'm not sure how to achieve this. Help is appreciable.

From what I have understood, you don't want every machine to download from the Ubuntu repositories, but only one machine should do the task. It'll handle 32bit and 64bit without any issues. Use one of the following apt-proxy, apt-cacher, apt-cacher-ng, approx I started with apt-cacher and faced update issues in long term use, so I moved to approx and was happy with it, but newer version presented a bit difficulty in the sense that it didn't run its own daemon. So I moved onto apt-cacher-ng which has been working well for quite some time now. Hope it helps.

Regards Vivek Kapoor http://exain.com I have used a simplistic approach by linking /var/cache/apt./archives to a common NFS mounted directory. Only requirement is that no root squash option is needed. It does not even matter which system is updated first as all subsequent updates find the package in the common cache.

There's a minor inconvenience in this approach even if we ignore the simultaneous downloading of files part. You would still have to update the package information (apt-get update) from Ubuntu repositories on all the machines as that data isn't in /var/cache/apt/archives :-) It's 6MB+ from what I can recall (if I exclude the sources).
