How to Install Python 3.14 on Ubuntu 24.04

Python is one of the most popular programming languages in the world, widely used for web development, data science, automation, and DevOps. With every new release, Python introduces performance improvements, security patches, and modern syntax features that make development smoother and faster.

This tutorial illustrates two methods of how to install it on your Ubuntu 24.04 OS.

Why Upgrade to Python 3.14?

Before diving into the commands, it’s worth understanding why upgrading to Python 3.14 is beneficial.

Some of the expected improvements in Python 3.14 include:

Performance boosts: Faster startup times and optimized memory usage.
Enhanced syntax features: Cleaner pattern matching and new language constructs.
Improved error messages: More readable and beginner-friendly tracebacks.
Security updates: Stronger hashing algorithms and better sandboxing support.

Python 3.14 is fully backward compatible with most 3.x scripts, but testing your projects in a virtual environment is still recommended before full migration.

Update and Upgrade Your System

Start by updating your Ubuntu 24.04 system to avoid package conflicts:

# apt update && sudo apt upgrade -y

Method 1: Install Python 3.14 Using Deadsnakes PPA (Recommended)

This method makes it easy to install Python 3.14 on Ubuntu 24.04 and be able to receive continued updates, bug fixes, and security updates.

The Deadsnakes PPA is a trusted third-party repository that provides newer versions of Python for Ubuntu systems.

First Add the Deadsnakes PPA to the APT package manager sources list:

# add-apt-repository ppa:deadsnakes/ppa -y

Press Enter to continue.

Once the repository has been installed, run an APT update to ensure that the newly imported PPA is reflected.

# apt update

Now you can install Python 3.14 with the following command:

# apt install python3.14 -y

Then verify the installation with the following command:

# python3.14 --version

You should see output similar to:

Python 3.14.0

If you have installed Python 3.14 using the APT package manager, the PIP will not be installed by default. To install pip3.14, run the following command:

# curl -sS https://bootstrap.pypa.io/get-pip.py | python3.14

You can check PIP for the Python 3.14 version using the following command:

# pip3.14 -V

pip 25.3 from /usr/local/lib/python3.14/site-packages/pip (python 3.14)

Method 2: Build Python 3.14 from Source

Also, you can compile Python 3.14 manually from the official source code. With this installation method, the main issue is that you cannot quickly update like the APT package manager and will need to recompile for any changes.

First, install the required prerequisite packages for the compilation of the Python 3.10 source code.

# apt install -y build-essential libssl-dev zlib1g-dev \
libncurses5-dev libncursesw5-dev libreadline-dev libsqlite3-dev \
libgdbm-dev libdb5.3-dev libbz2-dev libexpat1-dev liblzma-dev \
tk-dev libffi-dev uuid-dev wget

Now proceed and download the latest release version of Python from the Python official release page.

Alternatively, copy the download link for Python 3.14 gzipped tarball and use wget to pull it with the following command:

# cd /usr/src && wget https://www.python.org/ftp/python/3.14.0/Python-3.14.0.tgz

Once done, extract the archive:

# tar -xf Python-3.14.0.tgz

Now navigate into the extracted directory and run the configure script to check the required dependencies.

# cd Python-3.14.0

# ./configure --enable-optimizations --enable-shared

You can speed up the build process by using all CPU cores:

 make -j 6

Remember, the (-j) corresponds to the number of cores in your system to speed up the build time.

To find out how many cores you have on your system, execute the following code:

# nproc

Output:

We have six cores, so in the (make) command, we used (-j 6).

Once the build process has been completed, run the following command to complete the Python installation. Instead of overwriting the system version, we’ll install Python 3.14 as an alternative:

# make altinstall

The altinstall target prevents replacing /usr/bin/python3 and keeps your default Python intact.

Verify your installation:

# python3.14 --version

If everything went smoothly, you’ll see:

Python 3.14.0

Install Python Modules|Extensions

Modules and extensions can be installed using the Python Package manager (PIP).

Use the syntax below to install a Python module of choice.

# pip3.14 install module-name

In this tutorial, We will show you how to install a Python module plotly.

# pip3.14 install plotly

Output:

Collecting plotly
  Downloading plotly-6.4.0-py3-none-any.whl.metadata (8.5 kB)
Collecting narwhals>=1.15.1 (from plotly)
  Downloading narwhals-2.10.2-py3-none-any.whl.metadata (11 kB)

You can verify your module installation using the following command:

# pip3.14 list | grep plotly

---------------------- --------------------

Create a Virtual Environment

After successfully installing Python 3.14, it’s a best practice to create a virtual environment before installing any packages. Virtual environments allow you to isolate dependencies for each project preventing conflicts between system-wide and project-specific Python libraries.

The venv module is not included by default with the Python 3.14 installation, but you can install it manually:

# apt install python3.14-venv -y

This package provides the necessary tools to create and manage virtual environments.

You can create a virtual environment in your project directory. Navigate to your desired location and run:

# python3.14 -m venv myenv

Note: myenv is the name of your virtual environment (you can rename it).

To start using your isolated Python environment, activate it with the following command:

# source myenv/bin/activate

Once activated, your shell prompt should change to show the environment name, similar like this:

(myenv) root@linuxtuto:~#

To deactivate the virtual environment run the following command:

# deactivate

While the environment is active:

- All installed Python packages will stay local to the project.

- The global Python installation remains unaffected.

Optional: Set Python 3.14 as Default

Ubuntu 24.04 still ships with Python 3.12 by default. You can switch to Python 3.14 using update-alternatives safely:

# update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.12 1
# update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.14 2
# update-alternatives --config python3

And choose which one to use as Python3 via command:

# update-alternatives --config python3

Select Python 3.14 when prompted, then verify:

# python3 --version

Expected output:

Python 3.14.0

Conclusion

Installing Python 3.14 on Ubuntu 24.04 is simple using the Deadsnakes PPA or by compiling from source. The new release delivers performance improvements, better syntax, and modern features that make development faster and safer.

With Python 3.14 installed, you’re ready to build powerful applications, automate workflows, or explore AI projects with the latest language tools.
