|Ubuntu Flavours - Most prominent|
Lets say, you have Ubuntu 14.04 ISO and want to download Ubuntu GNOME 14.04. What will you do ? Download both of them completely ? That would work great, if you've got plenty of Internet Speed and Unlimited Bandwidth and patience too. But for people like me, who have slow internet connection or limited bandwidth, we cannot afford to do so. So, using this method, you can save your bandwidth and time. When I downloaded Ubuntu GNOME with having Ubuntu ISO image already with me, only 25% of the Ubuntu GNOME ISO needed to be downloaded and the rest was taken from the Ubuntu ISO that I already had.
What is zsync ?zsync is a file transfer program. It allows you to download a file from a remote server, where you have a copy of an older version of the file on your computer already. zsync downloads only the new parts of the file.
Installing Zsync :If you are Ubuntu or Ubuntu derivates, then you can install Zsync from the repository by issuing the following command :
sudo apt-get install zsyncFor all linux distros, you can download the tarball and install from it. Check out ZSync downloads page to know more.
Downloading different ubuntu flavours with Zsync :Thus you have an ubuntu ISO image already, and using this, you'll download the rest of the flavours.
You can download the different flavours using the following steps :
- Download any one flavour first. This will act as the base for downloading others.
- Then head to the Ubuntu releases page.
- And pick your next flavour and the release to download
- Then copy the link address for the zsync file.
- Open Terminal and type the following :
|Copy the Zsync file's address|
zsync <paste the zsync file link> -i <your base ISO file name>
zsync http://cdimage.ubuntu.com/kubuntu/releases/14.04/release/kubuntu-14.04-desktop-amd64.iso.zsync -i ubuntu-14.04-desktop-amd64.iso
|Downloading with Zsync|
Thats it, and after that you can also continue with the other flavours.
