@chrisgavin can you tell what's going wrong with the pip URL? It looks like we're using the correct one...

curl --location --fail https://bootstrap.pypa.io/2.7/get-pip.py

                                 Dload  Upload   Total   Spent    Left  Speed

Hi there!

The URL you are using to fetch this script has changed, and this one will no
longer work. Please use get-pip.py from the following URL instead:

    https://bootstrap.pypa.io/pip/2.7/get-pip.py

Hmm, that's annoying. It looks like they've changed it to have /pip/ at the start.

🤦 didn't spot the difference, thanks.

Closing in favour of #413.
