Sure, I can provide you with instructions on how to downgrade Python from version 3.8 to 3.7 on Ubuntu. Please note that downgrading Python versions can have implications on your system, and it’s essential to exercise caution. Also, some packages may not be compatible with the older version.
Here’s a step-by-step tutorial:
Step 1: Check Current Python Version
Before you proceed with the downgrade, it’s a good idea to check the current Python version.
This command will display the current Python version installed on your system.
Step 2: Update Package Lists
Make sure your package lists are up-to-date.
Step 3: Install Python 3.7
Ubuntu 20.04 LTS (Focal Fossa) comes with Python 3.8 by default, so we’ll need to add a repository that provides Python 3.7.
Step 4: Set Default Python Version
Now, update the alternatives to set Python 3.7 as the default version.
Step 5: Configure Python Version
Configure the alternatives and select Python 3.7.
You’ll see a list of installed Python versions. Choose the number corresponding to Python 3.7.
Step 6: Verify the Change
Verify that the Python version has been changed.
This command should now display Python 3.7.
Step 7: Update pip
The Python 3.7 installation might come with its own pip. Make sure it’s up-to-date.
Step 8: Clean Up
Optionally, you can remove Python 3.8 if you no longer need it.
Please note that downgrading Python may break certain applications or scripts that rely on features specific to Python 3.8. Always make sure that your applications are compatible with Python 3.7 before downgrading.

First, let’s confirm the currently installed Python version by running the following command in your terminal:
This command will display the installed Python version. If it’s Python 3.8, proceed with the downgrade.
We’ll need to add the deadsnakes PPA (Personal Package Archive) to install Python 3.7. Run the following commands:
This will install Python 3.7 alongside Python 3.8.
Verify that Python 3.7 is installed correctly by running:
This command should display the Python 3.7 version information.
Ubuntu uses the update-alternatives command to manage multiple versions of software installed on the system. We need to update the Python alternatives to make Python 3.7 the default version.
Run the following command:
