Installing Ubuntu Updates on Multiple Systems

Ubuntu

Ubuntu 12.04

Today I was installing Ubuntu in my Olives School lab. There are 20 systems in total. After installing it in the first PC, I ran the Update and there were 443 of them which amounted for 337MB approx. As it can be imagined it took some time to get the first PC updated. This was clearly not what I was going to do with the rest and I had to come up with a solution.

When Ubuntu downloads these updates, it places them in /var/cache/apt/archives/ folder. In fact even after installing updates, they are not removed from the system. So a solution was simple:

  • Copy all the downloaded packages to a USB
  • On the next PC, run the command:
    sudo cp [path-to-usb]/* /var/cache/apt/archives
  • Once all the files have been pasted, run the Update Manager tool and it will tell you that updates have been downloaded but not yet installed.
  • Click on Install 🙂
