OK thanks for the advice.

I started installing following the path ...

the first error I hit is:

...
   File "/opt/mailman/venv/lib/python3.9/site-packages/hyperkitty/lib/renderer.py", line 6, in <module>
     from mistune.plugins.extra import plugin_url
ModuleNotFoundError: No module named 'mistune.plugins.extra'

Sorry, that's https://gitlab.com/mailman/hyperkitty/-/issues/437

It is also not clear if you will also encounter https://gitlab.com/mailman/hyperkitty/-/issues/431

If your HyperKitty is version 1.3.5 installed from PyPI, the simplest solution is to downgrade mistune to 2.0.0rc1 in your venv

pip install mistune==2.0.0rc1

Alternatively you can downgrade to mistune<3.0

pip install mistune<3.0

But then you also need to ensure that line 7 in /opt/mailman/venv/lib/python3.9/site-packages/hyperkitty/lib/renderer.py is

from mistune.util import escape_html, escape_url

and not

from mistune.scanner import escape_html, escape_url
