Introduction

Are you experiencing a frustrating error message every time you start your Ubuntu 17.04 machine? The error "No module named 'six'" is a common issue that can be caused by various factors, including package-data-downloader crashes. In this article, we will delve into the possible causes of this error and provide step-by-step solutions to resolve it.

Understanding the Error

The error "No module named 'six'" typically occurs when a Python script or package is trying to import the 'six' module, but it is not installed or available in the Python environment. The 'six' module is a compatibility library that provides a way to write Python 2 code that is compatible with Python 3.

Possible Causes of the Error

  1. Missing 'six' Module: The most common cause of this error is that the 'six' module is not installed in the Python environment. This can happen if the package-data-downloader crashes or if the 'six' module is not included in the Python package.
  2. Package-Data-Downloader Crash: The package-data-downloader is a tool that downloads and installs packages from the Ubuntu repositories. If it crashes, it can leave behind a corrupted state that causes the 'six' module to be missing.
  3. Python Environment Issues: Issues with the Python environment, such as a corrupted Python installation or a mismatch between the Python version and the 'six' module, can also cause this error.
