How to upgrade python in linux

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 .

How to Update Python Version? — [Upgrade Python Version]

Are you looking to update Python version to the latest python version? Then this blog post will guide you with how to upgrade Python version.

List of content you will read in this article:

Python is an open-source high-level programming language that allows users to execute commands, plugins on their machine, and even software from several major suppliers. It means you can operate it on many different operating systems, including the Windows VPS Server. Python is a cross-platform programing language.

Pip is one of the best applications for Python package installation and administration. Pip’s popularity stems from the many apps that use this tool. Pip enables 3rd Party package installed to manage binary packages with the quickly configured package manager. Since Python’s latest releases have piping as normal, this guide will explain how to install PIP and how to update Python version with a complete step-by-step guide.

What is PIP?

PIP is a software management framework for installing and managing Python-written program packages. It is called the ‘preferred software installer’ or ‘Pip Installs Packages.’ PIP, used for Python, is a command-line interface for handling PyPI program installation. You might need to upgrade PIP if you’re using an earlier version of Python on Windows. Download the application file, open the command- line and start the installer to run PIP on Windows quickly. It will teach you how PIP is installed on Windows and how it can be modified, upgraded, and set up.

How to update Python on Windows Operating System?

There are two simple ways to update your current Python version with the latest one. They are as follows:

So let’s see how we can update the Python version with these two methods, one by one.

Method 1: Python update on Windows using the Python Installer

This method of updating the Python version will work if Python is installed or not on your System.

If Python is already installed on your system, you can check it using the python -V command.

Step 1: Download the Python installer from the Official Website of Python

The easiest way to update the Python version is to download the latest version from the official website ( https://www.python.org/downloads/ )

You can click on the Download Python 3.11.0 button, and it will download the latest compatible Python version for your system.

Step 2: Install the Downloaded Python Installer

After downloading the exe file, double-click on it to install Python.

Step 3: Install Python

Now, you can install the latest version of Python.

Check the “Add python.ext to PATH”, then click on the “ Install Now ” button.

This will start the installation process.

After processing, the latest version of Python will be installed on your system.

Click on the “Close” Button.

Step 4: Verify the Update

After successful installation, you can verify whether or not the latest version is installed on your system. To check the version, you can again run the same command, python -V , on the prompt command.

Now, you can see that it is showing the latest installed version, i.e., Python 3.11.0.

Note: If it still shows the old version, you may restart your system . Or uninstall the old version from the control panel .

Method 2: Install Python using Command Line Only using the Chocolatey Package Manager

Chocolatey is a Package Manager command line tool for windows, and we can use it to install software for our window system. In our case, we can use it to install Python or update the current version of Python.

Step 1 Open The Powershell as Administrator

To install Chocolatey, you need to open PowerShell as Administrator.

Step 2: Install the Chocolatey Package Manager Command

Now, you can install the Chocolatey package manager using the following command.

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString(‘https://community.chocolatey.org/install.ps1’))

Step 3: Verify the Chocolatey Installation

Now, you need to check whether Chocolatey has been installed successfully. To check it, run the “ choco ” command.

It is installed successfully because it is showing version Chocolatey v1.2.0.

Step 4: Update Python with Chocolatey

With the help of the choco upgrade command, we can update our current Python version.

Step 5: Verify the Version

You can again check the latest installed Python version using the following command.

Note: The old version of Python will remain on your system. You can uninstall the old version from the control panel.

How To Upgrade Python on macOS?

You can download the latest version of Python for macOS from the official Python website, similar to what you did on windows OS to update Python version on your system. To check whether it is updated to the lasted version or not, follow the below-listed commands to check the Python version.

If you want to execute this new Python release with the python command instead of python3, install an alias in your $HOME directory’s bash profile file.

Open the terminal window and type the following commands:

$ cd $HOME
$ nano .bash_profile

Then, at the bottom, add this segment.

Python 3.9 version can be checked using the following command.

How to Update Python version on LINUX?

Users can use the below listed Linux commands to upgrade Python version on the Linux server:

ppa:deadsnakes/ppa can be added to the system’s Software Sources to upgrade the machine with unsupported packages from this untrusted PPA.

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

This command is used to update the Python package.

$ sudo apt update
$ sudo apt install python3.9

Then, using the commands below, you can search the versions of your new and current Python installations:

This command will show you the following version of python installed in your system
