Pop!_OS is a popular operating system based on Ubuntu, and like most operating systems, it comes with a default version of Python installed. However, you may want to install a newer version of Python or multiple versions of Python on your system for different purposes.

Python is a popular programming language that is widely used in many fields, including data science, web development, and scientific computing. Pop!_OS is a popular operating system based on Ubuntu, and like most operating systems, it comes with a default version of Python installed. However, you may want to install a newer version of Python or multiple versions of Python on your system for different purposes.

In this article, we will explore three methods for installing Python 3 on Pop!_OS: using the Pop!_OS package manager, using `deadsnakes` PPA, and building Python from the source.

Method 1 – Using default package manager

Pop!_OS comes with a package manager called “apt” (Advanced Package Tool) that allows you to install and manage software packages. To install the latest version of Python using apt, you can use the following command:

sudo apt install python3

This will install Python 3 and its associated package manager “pip3” (Python Package Index), which you can use to install additional Python packages.

Method 2 – Using PPA (Personal Package Archive)

To install Python 3 on Pop!_OS using a Personal Package Archive (PPA), you can follow these steps:

  1. Open a terminal and update the package and install the software-properties-common package, which provides the “add-apt-repository” command that you will use to add the PPA: 
    sudo apt update && sudo apt install software-properties-common -y
  2. Add the `deadsnakes` PPA, which provides updated versions of Python: 
    sudo add-apt-repository ppa:deadsnakes/ppa
  3. Update the package list again to include the packages in the PPA and then install Python 3 using the apt package manager: 
    sudo apt update && sudo apt install python3.11

    Replace “3.11” with the desired version of Python.

  4. Verify that Python 3 was installed correctly by running the following command: 
    python3 --version

    You should see the version of Python that you installed.

Note that using a PPA is not the recommended method for installing Python on Pop!_OS, as it can introduce compatibility issues and security risks. It is generally better to use the package manager or Anaconda distribution to install Python.

Method 3 – Building Python from source

If you want to install a specific version of Python or customize your Python installation, you can build Python from source. To do this, you will need to download the source code from the Python website (https://www.python.org/downloads/) and follow the instructions in the “Building Python from source” section of the documentation (https://docs.python.org/3/using/unix.html#building-python).

  1. Download the required Python version 
    https://www.python.org/ftp/python/3.11.1/Python-3.11.1.tgz
  2. Extract the downloaded archive file 
    tar xzf Python-3.11.1.tgz -C /usr/src
  3. Switch to the extracted directory 
    cd /usr/src/Python3.11.1
  4. Build the Python source code and install it. 
    ./configure 
make 
make install
  5. Once the build and installation are completed successfully, verify the installed Python version. 
    python3.11 --version

Building Python from source can be a more advanced option, as it requires you to have a compiler and other dependencies installed on your system.

Regardless of which method you choose, it is important to note that Python 2 is no longer actively developed and it is recommended to use Python 3 for all new projects.

Conclusion

In this article, we have discussed three methods for installing Python 3 on Pop!_OS: using the Pop!_OS package manager, using the Anaconda distribution, and building Python from the source. Each method has its own advantages and drawbacks, and the appropriate method will depend on your specific needs and preferences. Using the Pop!_OS package manager or Anaconda distribution is generally the easiest and most reliable way to install Python while building Python from source allows for more customization and control.

Regardless of which method you choose, it is important to note that Python 2 is no longer actively developed and it is recommended to use Python 3 for all new projects.
