Section 1: Import Python PPA on Linux Mint 21 or 20
In this section, we’ll guide you through importing a Python PPA (Personal Package Archive) to install the latest version of Python 3.11 on your Linux Mint system. PPAs are widely used by the Linux community to distribute software packages that may not be available in the official repositories or to provide newer versions of existing packages.
Two branches are available for Python 3.11: the stable branch and the nightly branch. While the stable branch offers the most recent official release and receives regular updates, the nightly branch provides the latest development changes. We recommend using the stable branch for most users, as it offers a more stable and tested version of Python 3.11.
Option 1: Import Python Stable PPA on Linux Mint for Python 3.11
To import the stable PPA for Python 3.11, open a terminal and enter the following command:
sudo add-apt-repository ppa:deadsnakes/ppa -y
Option 2: Import Python Nightly PPA on Linux Mint for Python 3.11 (Upstream)
If you prefer to use the nightly PPA to access the latest development changes, enter the following command instead:
sudo add-apt-repository ppa:deadsnakes/nightly -y
Refreshing the APT Sources List
After importing the desired Python PPA, you’ll need to update your APT sources list to fetch information about the new packages available from the PPA. To do this, execute the following command:
sudo apt update

Section 3: Test Python 3.11 Shell on Linux Mint 21 or 20
After installing Python 3.11 on your Linux Mint system, ensuring everything is working as expected is important. In this section, we’ll walk you through the process of opening the Python 3.11 shell and exiting it when you’re done.
Opening the Python 3.11 Shell
To open the Python 3.11 shell, enter the following command in your terminal:
python3.11
This will launch the interactive Python 3.11 shell, where you can start typing Python commands, test your code, or explore the new features of Python 3.11.
Exiting the Python 3.11 Shell
When you’ve finished working with the Python 3.11 shell, you can exit it by entering the following command:
exit()
Alternatively, you can use the keyboard shortcut Ctrl+D to exit the shell.
Section 4: Install Pip via Python 3.11 on Linux Mint 21 or 20
To enhance your Python 3.11 experience on Linux Mint, it’s essential to have PIP (the Python Package Installer) installed. PIP allows you to install and manage additional Python packages and libraries easily. In this section, we’ll guide you through the process of installing and upgrading PIP for Python 3.11 on Linux Mint.
Install Python PIP on Linux Mint
PIP should already be installed for most users who have installed Python 3.11 using the Python PPA repository. However, if you need to install it manually, follow these steps:
First, run the following APT command to install PIP:
sudo apt install python3-pip
Download and Install PIP Manually on Linux Mint
If you encounter issues with the previous method, you can also download and install PIP manually:
Download the get-pip.py file using the wget command:
wget https://bootstrap.pypa.io/get-pip.py
After downloading the file, run the following command to install PIP:
python3 get-pip.py
Upgrade PIP to the Latest Version on Linux Mint
After installing PIP, it’s recommended to check for upgrades to ensure you have the latest version:
python3 -m pip install --upgrade pip
Verifying the Installed Version of PIP on Linux Mint
To verify the installed version of PIP, run the following command:
pip --version
Section 5: Additional Commands and Tips for Python 3.11 on Linux Mint

Managing Nightly and Stable PPA Repositories
If you have added the nightly PPA repository and would like to switch back to the stable version or remove it, follow these steps:
Remove the nightly PPA using the following terminal command:
To switch back to the stable version of the deadsnakes/ppa repository, use the following command:
sudo add-apt-repository ppa:deadsnakes/ppa -y
Switching Default Python Versions on Linux Mint 21 or 20
When you have multiple Python versions installed on your Linux Mint system, you may want to set a specific version as the default. To help you achieve this, we will walk you through the steps required to switch between different Python versions.
Adding Symbolic Links for Python Versions
First, you need to create symbolic links for each Python version separately. To accomplish this, run the following commands, customizing them as needed based on the Python versions installed on your system:
Note that the number at the end of each command (i.e., 1, 2, 3, etc.) represents the priority of the version. A higher number indicates a higher priority. In this example, Python 3.12 has the highest priority (7), and Python 2.7 has the lowest priority (1).
Switching to a Different Python Version on Linux Mint
To change the default Python version, enter the corresponding selection number in the following command:
sudo update-alternatives --config python
PinScreenshots demonstrating the steps to switch between alternative Python versions on Linux Mint 21 or 20 after installing Python 3.11.
For example, if you want to set Python 3.11 as the default, you would enter the number 3. The output of the command should resemble the following:
update-alternatives: using /usr/bin/python3.11 to provide /usr/bin/python (python) in manual mode
This output confirms that Python 3.11 has been set as the default version. By following these steps, you can easily switch between different versions of Python on your Linux Mint system.
Conclusion
In this guide, we have discussed the process of installing Python 3.11 on Linux Mint, along with some tips and tricks to enhance your Python development experience. Following the steps outlined, you can successfully set up Python 3.11 on your Linux Mint system and explore its features and capabilities. Remember to customize your Python environment to suit your preferences and take advantage of the various resources available to help you become more proficient with Python.
