Lubuntu is an official Ubuntu flavor based on the Lightweight X11 Desktop Environment (LXDE). The project’s goal is to provide a lightweight yet functional distribution. Lubuntu specifically targets older machines with lower resources, but also runs great on newer hardware. Along with a simple but usable graphical user interface, Lubuntu comes with a wide variety of applications chosen for their small
footprint so you can browse, email, chat, play, and be productive.
Lubuntu was recognized as part of the official Ubuntu family, meaning that the quality standards are acknowledged by the Ubuntu people. This also means, we can then release and maintain releases with long-term support.
LTS implies that, for 3 years (in our case), the part that comes from Lubuntu (LXDE, that is) is frequently updated and will be maintained for the upcoming three years. Bugs filed during this period do not expire. Canonical has resources allocated to bug fixing, meaning that the part that comes from Ubuntu (repositories, security updates and such) are maintained by them.
1.) Download ISO.
First you should decide what architecture that the target machine has, things like 32b or 64b and so on. You can visit the Lubuntu information page to see a list of the minimum requirements needed by the distribution along with links to more information and the download page.
2.) Create Boot Media.
Depending on the age of your target machine you may have a few options on what kind of boot media you create from the ISO image that you have downloaded. A bootable CD/DVD is the most common method used when installing Linux, however you may be able to create a bootable USB thumb drive that will help speed up the install a bit.
3.) Boot To Media.
Insert your install media into your target machine and power it on, you will see the language selection screen, press Enter here to see a list of installation options or alow the timer to expire and the live desktop will be loaded.
4.) Try Lubuntu.
if you see this screen then you can use the up and down arrow keys to navigate and select the top choice ‘Try Lubuntu without installing’. this is nice if you have never used Lubuntu and would like to get a quick peek at what you are about to install. remember you can install from the live desktop also.
5.) The Live Desktop.
This is what is called the live desktop, meaning that it is running right off of your installation media and nothing was written to your hard drive.
6.) Start The Installation.
Once you have had a chance to explore the operating system a bit and decided that you want to begin the installation, find the icon on the live desktop and double-click it to begin the process.
Select the default language for your system.
8.) Preparing to Install.
Here you have a few options to install updates while you are installing your new system as well as some rather handy third-party software. (optional) Select them both and click on Continue.
