Install Python 3.11 on Ubuntu 22.04|20.04

Welcome to our today’s guide on how to Install Python 3.11 on Ubuntu 22.04|20.04. The most recent version of Python, 3.11, has not yet reached final candidate status and is less stable than Python 3.10. However, this version has been released. Because of its straightforward and simple-to-learn syntax, Python, one of the most popular open-source object-oriented programming languages, is so popular.

Python was created by Guido van Rossum, a Dutch programmer. He is now employed by Microsoft, which anticipates greater enhancement and speed in the next version.

Features of Python 3.11

• Improved trace back error locations. Information for code objects in columns.
• Other Language Modifications
• Changes to Other Python Implementations.
• Updated Modules.
• Enhanced Modules that are fractions, optimizations, and asyncio.
• Speedier CPython quicker start-up.

Install Python 3.11 on Ubuntu 22.04|20.04

There are two methods of installing Python 3.11 on Ubuntu 22.04|20.04.

1. Install Python 3.11 using PPA
2. Install Python 3.11 manually

Method 1: Install Python 3.11 using PPA

First, install the package software-properties-common. This abstracts APT repositories and includes some useful scripts for managing software applications from third-party vendors, such as PPAs.

sudo apt install -y software-properties-common

To get Python3 up and running, make sure the local package index is up-to-date. Run the following command to update Ubuntu 22.04|20.04

sudo apt update -y
sudo apt upgrade -y

Perform system reboot.

sudo reboot

Now use the command below to add the ppa to your APT package source list.

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

Run an APT update after the repository has been imported to update your package manager to reflect the newly imported PPA.

sudo apt update

Verify Python installation:

$ python3.11 --version
Python 3.11.0

Method 2: Install Python 3.11 Manually

The default version available on the Ubuntu system is adequate for most programming tasks. Installing from the source provides the most recent version, customization options, a security patch, and new features.

First, Install Python 3.11’s necessary dependencies.

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev curl libbz2-dev pkg-config make -y

Visit Python official download’s page to obtain the latest version.

Change to the /tmp directory and use the wget command to download the Python 3.11 beta source file:

$ cd /tmp
$ wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0b1.tgz

Extract Python Archive:

tar -xf Python-3.11.*.tgz

As indicated below, navigate to the extracted directory and execute the ./configure -enable-optimizations command.

$ cd Python-3.11.*/
$ ./configure --enable-optimizations

Output.

Build Python 3.11 from the source as shown below after the check is finished. Keep in mind to use the -j switch to accelerate the procedure. This indicates how many cores your machine has. The nproc command displays the system cores.

make -j 4

Install Python 3.11 Supporting Packages

Several more packages are frequently required for Python applications to function properly. These auxiliary packages include virtualenv, distutils, and python-dev. They must be installed along with your latest Python upgrade.

Run the following command to install:

sudo apt install python3.11-dev python3.11-venv python3.11-distutils python3.11-gdbm python3.11-tk python3.11-lib2to3 -y

Well done on finishing your job!
