Ubuntu Linux Installation Tutorial Overview

This video tutorial provides a detailed, step-by-step guide on installing Ubuntu Linux Desktop 20.04 LTS to set up a programming environment tailored for Python-based tasks such as data collection and modeling.

Key Topics Covered

Ubuntu Linux Installation

Introduction to Ubuntu as a Linux distribution suitable for programming and data work.
Downloading the Ubuntu ISO image, with 20.04 LTS recommended for long-term support.
Two main installation approaches:
1. Direct installation on a laptop or desktop (either dual boot or full install).
2. Installation inside a virtual machine using VirtualBox to avoid modifying the host operating system.

VirtualBox Setup

Downloading and installing VirtualBox on Linux, Windows, or macOS.
Creating a new virtual machine configured for Linux/Ubuntu 64-bit.
Allocating RAM based on system capacity (typically between 1–3 GB).
Creating a virtual hard disk:
- Format: VDI (VirtualBox Disk Image)
- Storage: Dynamically allocated
- Recommended size: At least 10 GB

Ubuntu Installation in VirtualBox

Selecting the downloaded Ubuntu ISO as the installation media.
Navigating the installation interface and options:
- Choosing between minimal and normal installation:
  - Minimal excludes office software, games, and media players.
- Partitioning strategy:
  - Always select “Something else” for manual partitioning to maintain control and avoid data loss.
  - Create a swap partition equal in size to the allocated RAM.
  - Create an ext4 partition mounted at root (/).
- Handling bootloader location carefully.
- Awareness of UEFI and Secure Boot considerations when installing on physical hardware.

Post-installation Setup

Creating a username and password for system login.
Verifying internet connectivity inside the virtual machine using terminal commands (e.g., ping).
Preparing the system for future Python and library installations.

Additional Notes

Installation typically takes 30–40 minutes, depending on system speed.
When installing Ubuntu alongside an existing OS on physical hardware, users should be cautious to avoid data loss.
Installing Ubuntu inside a virtual machine is safer and more platform-agnostic.

Future Tutorials

Installing Python and essential Python libraries for programming tasks will be covered in upcoming tutorials.
