Resolving "ImportError: No module named 'encodings'" in Python After Ubuntu Upgrade

The issue arises when the locale encoding cannot be obtained, resulting in the error message "ImportError: No module named 'encodings'." This issue can persist despite reinstalling Python and setting environmental variables.

Solution for Python-3:

• Remove virtual environment files: rm -rf venv
• Recreate virtual environment: virtualenv -p /usr/bin/python3 venv/
• Activate virtual environment: source venv/bin/activate
• Install required packages: pip install -r requirements.txt

Additionally, as mentioned in the release notes for Ubuntu Xenial Xerus, it may be necessary to edit the file /etc/default/locale and ensure that the LANGUAGE and LC_ALL variables are set to the desired locale.

After following these steps, the issue should be resolved, allowing Python to run without encountering the "ImportError: No module named 'encodings'" message.
