Python (v3.10 or earlier): You need python to be available somewhere in your shell path.

Recent versions of Ubuntu default to python and point to Python 3. If not, you can install a new version of Python, and use pyenv to manage multiple Python versions. Ensure you're using Python 3.10 or earlier.

Hugo: Install the hugo_extended_0.125.6 version from the official Hugo releases for your Linux machine architecture. Make sure the hugo binary is available in the shell path.

Go: Install latest Go from the official Go website.

Git client: Ubuntu includes Git by default, but ensure you have the latest version (sudo apt-get install git).
