How to Install Python on Ubuntu 24.04

When you start a Python project on Ubuntu 24.04, the first question is usually whether the system Python is enough or whether you need a newer interpreter. Ubuntu already includes Python 3.12, but you may still need to install pip, the venv module, or a separate Python version such as 3.13 or 3.14.

This guide explains how to install Python on Ubuntu 24.04 using the default Ubuntu packages, the deadsnakes PPA, and a source build. It also shows how to create a virtual environment so project packages do not affect the system Python.

Ubuntu 24.04 Default Python Version #

Ubuntu 24.04 ships with Python 3.12 as the default Python 3 interpreter. To check the version on your system, run:

python3 --version

Python 3.12.3

The exact patch version may change as Ubuntu publishes security updates, but the default interpreter remains Python 3.12. For most system scripts and many development tasks, this version is enough.

Do not replace the /usr/bin/python3 interpreter. Ubuntu tools such as apt, system maintenance scripts, and desktop utilities expect the distribution-provided Python version. If you need a newer Python release, install it alongside the default interpreter and call it by its versioned command, such as python3.13 or python3.14.

Quick Reference #

Installing the Default Python Packages #

If you only need the Python version that comes with Ubuntu 24.04, install the standard Python tooling from the Ubuntu repositories. This gives you pip3 and the venv module for creating isolated project environments.

First, update the package index:

sudo apt update

Install pip and the virtual environment module:

sudo apt install python3-pip python3-venv

Verify the installed commands:

python3 --version
pip3 --version

On Ubuntu 24.04, python3 points to Python 3.12. The pip3 command installs packages for the system Python environment, but Ubuntu protects system-managed Python packages from accidental changes. For project dependencies, use a virtual environment instead of installing packages globally with pip3.

Create a virtual environment with the default Python:

python3 -m venv myproject

Activate it:

source myproject/bin/activate

Inside the environment, python and pip point to the isolated project environment:

python --version
python -m pip --version

When you are done working in the project, deactivate the environment:

deactivate

Installing Python from the Deadsnakes PPA #

The deadsnakes PPA provides newer Python versions packaged for Ubuntu. Use this method when you need Python 3.13, Python 3.14, or another supported version alongside Ubuntu’s default Python 3.12.

The PPA does not replace the system Python. It installs versioned commands such as python3.13 and python3.14, which is the safer approach on Ubuntu.

1. Install the prerequisites and add the PPA:

   Terminal

   sudo apt update
   sudo apt install software-properties-common
   sudo add-apt-repository ppa:deadsnakes/ppa

   Press Enter when prompted to confirm.

2. Install Python 3.13:

   Terminal

   sudo apt update
   sudo apt install python3.13

   To install Python 3.14 instead, replace python3.13 with python3.14:

   Terminal

   sudo apt install python3.14

3. Verify the installation:

   Terminal

   python3.13 --version

   The command prints the installed Python 3.13 patch release. You can also confirm the binary location:

   Terminal

   which python3.13

4. Install the venv module for the same interpreter:

   Terminal

   sudo apt install python3.13-venv

   If you installed Python 3.14, use:

   Terminal

   sudo apt install python3.14-venv

5. Create a virtual environment and use pip inside it:

   Terminal

   python3.13 -m venv myproject
   source myproject/bin/activate
   python -m pip install --upgrade pip

Installing Python from Source #

Compiling Python from source allows you to install any version and customize the build options. However, you will not be able to manage the installation through the apt package manager.

The following steps show how to compile Python 3.14.4. If you are installing a different version, replace the version number in the commands below.

1. Install the libraries and dependencies required to build Python:

   Terminal

   sudo apt update
   sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev liblzma-dev

2. Download the source code from the Python download page using wget :

   Terminal

   wget https://www.python.org/ftp/python/3.14.4/Python-3.14.4.tgz

3. Extract the archive :

   Terminal

   tar -xf Python-3.14.4.tgz

4. Navigate to the source directory and run the configure script:

   Terminal

   cd Python-3.14.4
   ./configure --enable-optimizations

   The --enable-optimizations flag runs profile-guided optimization tests, which makes the build slower but produces a faster Python binary.

5. Start the build process:

   Terminal

   make -j $(nproc)

   The -j $(nproc) option uses all available CPU cores for a faster build.

6. Install the Python binaries using altinstall. Do not use install, as it overwrites the system python3 binary and can break system tools that depend on it:

   Terminal

   sudo make altinstall

7. Verify the installation:

   Terminal

   python3.14 --version

   output

   Python 3.14.4

Setting Up a Virtual Environment #

After installing a new Python version, create a virtual environment for your project to keep dependencies isolated:

python3.13 -m venv myproject

Activate the virtual environment:

source myproject/bin/activate

Your shell prompt will change to show the environment name. Inside the virtual environment, python and pip point to the version you used to create it.

For a source-built Python 3.14 installation, use the versioned command:

python3.14 -m venv myproject

To deactivate the virtual environment:

deactivate

For more details, see our guide on how to create Python virtual environments .

Optional: Uninstalling the PPA Version #

To remove the PPA version:

sudo apt remove python3.13 python3.13-venv

To remove the PPA itself:

sudo add-apt-repository --remove ppa:deadsnakes/ppa

Troubleshooting #

python3 already exists after installation
This is expected. Ubuntu 24.04 includes Python 3.12 by default, so installing the default packages may only add missing tools such as pip3 or venv.

pip reports an externally managed environment
Ubuntu protects system-managed Python packages. Create a virtual environment with python3 -m venv myproject, activate it, and install packages with python -m pip install package-name inside the environment.

No module named venv
Install the matching venv package. For Ubuntu’s default Python, run sudo apt install python3-venv. For Python 3.13 from the PPA, run sudo apt install python3.13-venv.

Unable to locate package python3.13 or python3.14
Run sudo apt update after adding the deadsnakes PPA. If the package is still unavailable, check that the PPA supports your Ubuntu release and CPU architecture.

python3 still shows Python 3.12
The python3 command should continue to use Ubuntu’s default interpreter. Run the newer version with its versioned command, such as python3.13 or python3.14.

FAQ #

Should I use the PPA or build from source?
Use the Ubuntu packages if Python 3.12 is enough. Use the deadsnakes PPA when you need a newer packaged interpreter such as Python 3.13 or 3.14. Build from source only if you need a specific upstream patch release or a custom build configuration.

Will installing a new Python version break my system?
No. Both methods install the new version alongside the system Python 3.12. The system python3 command is not affected. You access the new version with python3.13 or python3.14.

How do I make the new Python version the default?
You can use update-alternatives to configure it, but this is not recommended. Many Ubuntu system tools depend on the default python3 being the version that shipped with the OS. Use virtual environments instead.

How do I install pip for the new Python version?
The recommended approach is to use a virtual environment. Install python3.13-venv, create a venv, activate it, and use python -m pip inside the environment.

What is the difference between install and altinstall when building from source?
altinstall installs a versioned binary such as python3.14 without creating a python3 symlink. install creates the symlink, which overwrites the system Python and can break Ubuntu system tools.

Does Ubuntu 24.04 include pip by default?
Ubuntu 24.04 includes Python 3.12 but does not include pip in the base installation. Install it with sudo apt install python3-pip. For newer Python versions, use python3.13 -m pip inside a virtual environment.

Conclusion #

Stick with Ubuntu’s Python 3.12 plus python3-pip and python3-venv for most projects. Reach for the deadsnakes PPA when a project pins to 3.13 or 3.14, and build from source only for a specific upstream patch.
