Upgrade Python to latest version (3.10) on Ubuntu Linux

Linux systems come with Python install by default, but, they are usually not the latest. Python also cannot be updated by a typical apt upgrade command as well.

To check the version of Python installed on your system run

python keyword is used for Python 2.x versions which has been deprecated

1. Update Python to the latest version
2. Fix pip & other Python related issues
3. While doing the above two, ensure your Ubuntu which is heavily dependent on Python does not break

Updating Python to the latest version

Ubuntu’s default repositories do not contain the latest version of Python, but an open source repository named deadsnakes does.

Python3.10 is not officially available on Ubuntu 20.04, ensure you backup your system before upgrading.

Step 1: Check if Python3.10 is available for install

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

Check if Python 3.10 is available by running

This will produce the below result, if you see python3.10 it means you can install it

Step 2: Install Python 3.10

Now you can install Python 3.10 by running

sudo apt install python3.10 

Now though Python 3.10 is installed, if you check the version of your python by running python3 —version you will still see an older version. This is because you have two versions of Python installed and you need to choose Python 3.10 as the default.

Step 3: Set Python 3.10 as default

Steps beyond here are tested on Ubuntu 20.04 in VM & WSL2, but are experimental , proceed at your own risk.

Changing the default alternatives for Python will break your Gnome terminal. To avoid this, you need to edit the gnome-terminal configuration file.

Open the terminal and run:

sudo nano /usr/bin/gnome-terminal 

In first line, change #!/usr/bin/python3 to #!/usr/bin/python3.8 . Press Ctrl +X followed by enter to save and exit.

Then save and close the file.

Next, update the default Python by adding both versions to an alternatives by running the below

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 Now run

sudo update-alternatives --config python3 

Choose the selection corresponding to Python3.10 (if not selected by default).

Now run python3 —version again and you should see the latest Python as the output.

Fix pip and disutils errors

Installing the new version of Python will break pip as the distutils for Python3.10 is not installed yet.

Fix Python3-apt

Running pip in terminal will not work, as the current pip is not compatible with Python3.10 and python3-apt will be broken, that will generate an error like

Traceback (most recent call last): File "/usr/lib/command-not-found", line 28, in <module> from CommandNotFound import CommandNotFound File "/usr/lib/python3/dist-packages/CommandNotFound/CommandNotFound.py", line 19, in <module> from CommandNotFound.db.db import SqliteDatabase File "/usr/lib/python3/dist-packages/CommandNotFound/db/db.py", line 5, in <module> import apt_pkg ModuleNotFoundError: No module named 'apt_pkg' 

To fix this first remove the current version of python3-apt by running

sudo apt remove --purge python3-apt 

DO NOT RUN sudo apt autoremove as it will remove several packages that are required. This may break your system if you’re using GUI, if you’re on WSL2 you can proceed.

Finally, reinstall python3-apt by running

sudo apt install python3-apt 

Install pip & distutils

Running pip will still throw an error pip: command not found . We need to install the latest version of pip compatible with Python 3.10.

Also, if try to manually install the latest version of pip, it will throw an error like

ImportError: cannot import name 'sysconfig' from 'distutils' (/usr/lib/python3.10/distutils/__init__.py) 

Or you might also see an error stating No module named ‘distutils.util’ . This is because the distutils module is not installed yet, to install run the below command

sudo apt install python3.10-distutils 

Now you can install pip by running

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py sudo python3.10 get-pip.py 

If you get an error like bash: curl: command not found then you need to install curl first by running sudo apt install curl

Now you can run pip and you should see the output of pip —version

Fix pip-env errors when using venv

When you try to create a new virtual environment using python -m venv env , you may into the following error.

Error: Command -Imensurepip--upgrade--default-pipYou can fix this by reinstalling venv by running

sudo apt install python3.10-venv 

All should be done now. It is complicated, but this is how you update Python to latest version.

Extra

If you have oh-my-zsh installed, you can avoid typing out python3 by running

Now you can run your files with py or python .

User

On many systems Python comes pre-installed, you can try running the python command to start the Python interpreter to check and see if it is already installed. On windows you can try the py command which is a launcher which is more likely to work. If it is installed you will see a response which will include the version number, for example:

Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information.

If you don’t see this, you will need to install Python on your system.

If the version number is Python 2.x.y (where x and y are any number) you are using Python 2 which is no longer supported and is not a good choice for development. You can try running python3 to see if there is also a Python 3.x.y version installed, if not you’ll want to install the latest version of Python.

If you do not have Python installed or need a newer version you can go to:

which will provide a button to download an installer for your particular system. The Python documentation also has a detailed guide on how to install and setup Python here:

Below are some system specific notes to keep in mind.

Windows

On Windows the most stable build is available from the official download page

You should download and run the installer from that page to get the latest version of Python for your system. You can refer to the Python documentation for more details on the installation process and getting started:

Mac

For macOS 10.9 (Jaguar) up until 12.3 (Catalina) the operating system includes Python 2, which is no longer supported and is not a good choice for development. You should go to do the downloads page: https://www.python.org/downloads/ and download the installer.

For newer versions of macOS, Python is no longer included by default and you will have to download and install it. You can refer to the Python documentation for more details on the installation process and getting started:

Linux

On most Linux distributions Python comes pre-installed and/or available via the distribution’s package managers. Below are some common examples, but refer to your specific distribution’s documentation and package list to get the most up to date instructions.

If you’d like to download and build Python from source (or your distribution’s package manager does not include a version of Python you need) you can download a source tarball from the general download page: https://www.python.org/downloads/

Red Hat, CentOS, or Fedora

dnf install python3 python3-devel

Debian or Ubuntu

apt-get install python3 python3-dev
