Kolibri 0.15.2 Python 3.10 error on Ubuntu 22.04 "ImportError: cannot import name 'Iterator' from 'collections' (/usr/lib/python3.10/collections/__init__.py)"

This promising work from earlier in April seemed tailored to getting Kolibri 0.15.2 working with Python 3.10? [CLARIF: No, Kolibri seems to be deferring support for Python 3.10 until a later date]

• PR #9296

Somehow however the just-released Kolibri 0.15.2 (https://learningequality.org/r/kolibri-deb-latest) appears to install on Ubuntu Desktop 22.04 on x86_64 (as part of Internet-in-a-Box) — but then serious Python 3.10 problems appear:

Likewise systemctl start kolibri fails, leading to this systemctl status kolibri output/trace:

(And hopefully 0.15.3 will be posted to https://learningequality.org/download/ shortly, to mainline this for others!)

Done & done! 🙂

Confirmed: Kolibri 0.15.3 now works on Ubuntu 22.04 (and Python 3.10) with https://internet-in-a-box.org

(And hopefully 0.15.3 will be posted to https://learningequality.org/download/ shortly, to mainline this for others!)
