Beta: Python 3 migration

python3_1

Today, I’m here to announce codebase migration to Python 3 for all CloudLinux userspace utilities. All packages are available from our updates-testing repository.

As you may already know, Python 2 support ended on New Year’s Day 2020. And we at CloudLinux are ready to remove some of the pitfalls and imperfections of Python 2 and stay secured and updated with the new Python 3.

I also should mention that the alt-python27-cllib package will be replaced with the alt-python-cllib package as we announced earlier.

If you encounter any issues, do not hesitate and reach out to our support team at https://cloudlinux.zendesk.com/.
