Install Anaconda in Ubuntu 22.04 – Tutorial for Beginners

You might find Anaconda useful if you are interested in data science, machine learning, or scientific computing. Anaconda is a widely recognized Python distribution that simplifies package management and deployment. In this guide, you will learn how to install Anaconda on Ubuntu 22.04, one of the latest long-term support (LTS) versions of the well-known Linux distribution.

Advantages of Anaconda

  • Before we begin the installation process, let’s briefly discuss why Anaconda is a popular choice among Python developers and data scientists:
  • Package Management: Anaconda simplifies package management with its package manager, Conda. Conda allows easy installation, updating, and removal of packages while ensuring compatibility and reproducibility of Python environments.
  • Python Environment Management: Anaconda allows for creating isolated Python environments, essential for managing different Python versions and dependencies for multiple projects.
  • Data Science Ecosystem: Anaconda includes commonly used libraries and tools for data science like NumPy, pandas, SciPy, scikit-learn, and Jupyter Notebook.
  • Cross-Platform: Anaconda is a versatile platform for Windows, macOS, and Linux, suitable for diverse development environments.
  • Community and Support: Anaconda has a thriving community with ample documentation, tutorials, and user support.

Now, let’s proceed with the installation.

Steps To Install Anaconda in Ubuntu 22.04

Step 1: Upgrade the System Packages List

Before installing any software, ensuring your system’s package list is current is essential. Open your terminal and run:

sudo apt update

This command refreshes the list of available packages.

Step 2: Install Curl and bzip

Curl and bzip2 are required to download and extract the Anaconda installer. Install them by running:

sudo apt install curl bzip2

or

sudo apt install curl bzip2 -y

These packages are essential for the installation process. You can use the -y flag to automatically answer ‘yes’ to the confirmation prompt that appears when installing packages. With this flag, you don’t need to confirm the installation manually; it will proceed automatically.

This will download the Anaconda installer script to your current directory, and you can proceed with the installation steps.

Step 4: Verify Data Integrity

To ensure the downloaded installer is not corrupted, verify its data integrity using SHA-256 checksums. Run the following command :

sha256sum anaconda3.sh

Compare the output with the checksum provided on the Anaconda website.

Ensure you download the correct Anaconda version, verify the installer’s checksum, and avoid using sudo. Check for sufficient disk space and read the prompts to avoid conflicts with existing Python installations.
