sudo apt install software-properties-common

Step 2 – Enable Repository#

After that add the deadsnakes PPA to your system’s sources list by typing:

sudo add-apt-repository ppa:deadsnakes/ppa

Hit the Enter when you get prompt.

Step 3 – Install Python 3.11#

Once the repository enabled you can install the Python 3.11 by running below command:

sudo apt update

sudo apt install python3.11

Step 4 – Verify Installation#

To verify the installation, you would type:

python3.11 --version

Install Python 3.11 on Ubuntu from Source#

You can install the latest version of Python and customize the build options by compiling the Python from source. Below are the steps to install Python 3.11 from Python source:

Step 1 – Install dependencies#

You should install the required dependencies to build python. Run the following commands:

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

Step 2 – Download source code#

After that download the latest source code from Python download page using wget:

wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz

Once the download is finished, extract the gzipped archive:

tar -xf Python-3.11.0.tgz

Step 3 – Configure script#

Go to the Python source directory and execute the configure script. It will do few checks for dependencies.

cd Python-3.11.0

./configure --enable-optimizations

The --enable-optimizations option optimizes the Python binary by running multiple tests. This makes the build process slower.

Step 4 – Start build process#

You would run the following command to start the build process for python:

make -j 12

For faster build time, modify the -j to correspond to the number of cores in your processor. You can find the number by typing nproc.

Step 5 – Install Python#

Once the build process is complete, install the Python binaries by typing:

sudo make altinstall

That’s it. Python 3.11 has been installed from source and ready to be used. Verify the installation by typing:
