Install Lubuntu 20.04 – A Lightweight Linux Desktop Environment

Lubuntu is an open-source distribution of Linux based on Ubuntu. It is lightweight, fewer resource hungry, more energy-efficient and uses an LXQT desktop environment.

The initial release of Lubuntu has LXDE as their desktop environment but with version 18.04 it uses LXQT. If you are an existing user of Lubuntu who uses LXDE then migrating to higher versions that use LXQT will be challenging.

In that case, you have to opt for a fresh copy of Lubuntu 20.04. Let’s take a look at what official documentation has to say about upgrading from LXDE to LXQT.

Due to the extensive changes required for the shift in desktop environments, the Lubuntu team does not support upgrading from 18.04 or below to any greater release. Doing so will result in a broken system. If you are on 18.04 or below and would like to upgrade, please do a fresh install.

A good place to start before installing is the Lubuntu manual. It has a good set of documentation to understand what this distro has to offer. Since Lubuntu is a derivative of Ubuntu and it has access to Ubuntu software repositories through discovery software center, synaptic package manager, and apt package manager. It comes with Linux kernel 5.0.4-42-generic and bash version 5.0.17.

The latest version of Lubuntu is 20.04 LTS and it is supported till April 2023.

Ubuntu and some of its derived versions use Ubiquity as an installer but Lubuntu uses the Calamares installer.

If you are a windows user you can use Rufus to create a bootable usb drive to install the OS.

1. Once you boot the drive, it will prompt with options. Choose “Start Lubuntu”.
