The latest version of Python is 3.11.4. I use Debian 11 for a lot of my work , and would like to have the latest Python 3.11.4. Unfortunately, Debian 11 stable includes a much older version. This tutorial will help you install Python 3.11.4 on Debian 11.
I use Linode for my web hosting. It is an awesome hosting company. I use the unmanaged plan, so that means I get to install Nginx, configure the system and install the latest and greatest version of Python, which is 3.11.4.
Go get your Linode account with $100 free credits for 60 days.

Download Python 3.11.4 source
Python 3.11.4 was released on June 6, 2023. The latest Python source code is available here.
Download and extract the Python source code.
cd /tmp/ wget https://www.python.org/ftp/python/3.11.4/Python-3.11.4.tgz tar -xzvf Python-3.11.4.tgz cd Python-3.11.4/
Install the build tools
Now, install the build tools. The build tools includes gcc, make, zlib, ssl libraries and other libraries.
sudo apt update sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev
If you are prompted to install other dependencies, select yes.
Configure, make and make install
make. You can make the build using
nproc, which returns the number of CPUs.
make -j `nproc`
The default Python installation is
/usr/bin. If you want to install Python under
/usr/local/bin instead of overwriting the default, do this:
sudo make altinstall
This will install Python at
/usr/local/bin/python3.11. To test the version, run this:
You will get this output:
Make Python 3.11.4 the default version
To make the default version of Python 3.11.4, run this:
sudo ln -s /usr/local/bin/python3.11 /usr/local/bin/python
This creates a bunch of softlinks and links the latest Python to
Test whether Python 3.11.4 is the default version:
$ ls -al /usr/local/bin/python lrwxrwxrwx 1 root root 25 Jul 5 19:33 /usr/local/bin/python -> /usr/local/bin/python3.11 $ /usr/local/bin/python3.11 -V Python 3.11.4
The output will be:
Python 3.11.4 (main, Jul 5 2023, 19:29:26) [GCC 10.2.1 20210110]
So, at this point, Python 3.11.4 has been set as the default version of Python.
