Proper way to install pip on Ubuntu

On Ubuntu, you can install pip using the package manager, as pip is usually available in the official repositories. Here's how you can properly install pip on Ubuntu:

  1. Update Package Lists: Before installing any new packages, it's a good practice to update your package lists:

    sudo apt update

  2. Install pip: Use the following command to install pip:

    sudo apt install python3-pip

    This command installs pip for Python 3. The package name python3-pip ensures that pip is associated with Python 3.

  3. Verify Installation: After the installation is complete, you can verify that pip is installed by checking its version:

    pip3 --version

    The output should display the version of pip along with the version of Python it's associated with.

  4. Upgrade pip (Optional): While installing, the package manager might install an older version of pip. You can upgrade pip to the latest version using:

    sudo pip3 install --upgrade pip

    This ensures that you have the latest version of pip with the most recent bug fixes and features.

Please note that the package names and installation commands might differ slightly if you're using a different version of Ubuntu or if your system has specific configurations. The provided instructions are suitable for Ubuntu versions 16.04 and later.

If you're working with virtual environments, remember that you should activate your virtual environment first and then use pip without sudo to install packages within the virtual environment.
