Introduction

Downgrading a system's Python version can be a complex process, especially when it comes to Ubuntu. In this article, we will discuss the issue of terminal stops launching after downgrading Python version on Ubuntu. We will explore the possible causes and provide a step-by-step guide to resolve the issue.

Background

Upgrading to a newer version of Ubuntu can sometimes cause issues with existing software. In this case, the user upgraded from Ubuntu 22.04 to 24.04, which resulted in a higher version of Python (3.12.x). However, this caused issues with the cqlsh command, which requires a lower version of Python.

Symptoms

The user reported that after downgrading Python, the terminal stops launching. This is a critical issue, as it prevents the user from accessing the command line interface (CLI) and performing any tasks.

Possible Causes

There are several possible causes for this issue:

  1. Incompatible Python versions: The downgraded Python version may not be compatible with the existing system libraries and dependencies.
  2. Broken package dependencies: The downgraded Python version may have broken package dependencies, which can cause issues with the terminal.
  3. Corrupted system files: The downgrading process may have corrupted system files, which can prevent the terminal from launching.

Troubleshooting Steps

To resolve the issue, follow these troubleshooting steps:

Step 1: Check Python Version

First, check the Python version using the following command:

python --version

This will display the current Python version.

Step 2: Check Package Dependencies

Next, check the package dependencies using the following command:

sudo apt-get check

This will display any broken package dependencies.

Step 3: Reinstall Python

If the package dependencies are broken, try reinstalling Python using the following command:

sudo apt-get install --reinstall python3

This will reinstall Python and its dependencies.

Step 4: Reinstall System Libraries

If the issue persists, try reinstalling system libraries using the following command:

sudo apt-get install --reinstall libpython3*

This will reinstall system libraries related to Python.

Step 5: Reconfigure Terminal

If the issue still persists, try reconfiguring the terminal using the following command:

sudo dpkg-reconfigure -a

This will reconfigure the terminal and its dependencies.
