New installation, new issue: mailman3 migrate -- no module CommonMark
My Ubuntu 24.04 installation is working great, and I have a list running perfectly. I'm now trying to install mailman3 on an older server, this time runing ubuntu 22.04. I'm following the venv installation instructions again, but suddenly came up with a new error.
I've made it to the "Run database migrations" section I run mailmanweb-migrate and get:
(venv) mailman@mail:~$ mailman-web migrate Traceback (most recent call last): File "/opt/mailman/venv/lib/python3.10/site- packages/django/template/backends/django.py", line 128, in get_package_libraries module = import_module(entry[1]) File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1050, in _gcd_import File "<frozen importlib._bootstrap>", line 1027, in _find_and_load File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 688, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 883, in exec_module File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "/opt/mailman/venv/lib/python3.10/site- packages/postorius/templatetags/markdown.py", line 21, in <module> from readme_renderer import markdown as md_render File "/opt/mailman/venv/lib/python3.10/site- packages/readme_renderer/markdown.py", line 16, in <module> from CommonMark import commonmark ModuleNotFoundError: No module named 'CommonMark'
The above exception was the direct cause of the following exception:

ImportError raised when trying to load 'postorius.templatetags.markdown': No mod ule named 'CommonMark'
I know nothing about CommonMark.
Since I've suffered the error cascade problem of trying to fix things and just making it worse, I stopped here.
Can I ignore this error, or what can I do to fix it?
Thanks!

What is your version of readme_renderer? I don't see readme_renderer importing from CommonMark in any recent version.

Which is over 6 years old. How did that get installed? Current version is 44.0. There may or may not be an issue with the current version as it imports cmarkgfm which is in the venv of all the MM 3 installations I support, but I don't know how it gets there as even though readme_renderer imports it, it is not listed as required by readme_renderer or anything else.
In any case, in your venv, do
pip install --update readme_renderer cmarkgfm

That did the trick, though I had to use --upgrade instead of --update. Thanks... Now on to the next step.
I don't know about the libraries.
Here's my mailman info. It seems like the right version of python.
(venv) mailman@mail:~$ mailman info GNU Mailman 3.3.10 (Tom Sawyer) Python 3.10.12 (main, Sep 11 2024, 15:47:36) [GCC 11.4.0] config file: /etc/mailman3/mailman.cfg db url: postgresql://mailman:qazASD%401cko@localhost/mailman devmode: DISABLED REST root url: http://localhost:8001/3.1/

Thanks for your help!

My bad. Of course I meant --upgrade.
