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.
