Save time and bandwidth when updating multiple Ubuntu machines: Cache packages locally with Apt-cacher

Ubuntu has become the most popular version of Linux for various reasons: technically, it's based on Debian, an excellent foundation for a Linux distro; but also its included applications and package manager offer exceptional ease of use for newbies without compromising power for experienced users. Maximize your use of what is arguably the best Linux for desktops and laptops with 100 quick tips and tricks from Ubuntu Hacks. The hacks cover tasks such as: installing Ubuntu; using its powerful multimedia features; taking Ubuntu on the road with Wi-Fi; running Ubuntu with virtualization technology; Ubuntu system security; and setting up a Ubuntu-powered server. Save time and bandwidth when updating multiple Ubuntu machines with this sample hack: with Apt-cacher running only on one machine and all your other machines configured to fetch packages through it, you can download new packages only once and install them on every machine on your network. Apt-cacher works by intercepting requests for packages and fetching them on behalf of local machines, while simultaneously storing them on disk in case other machines later ask for the same package.
