This is the first time I am seeing this with MM3 so maybe it's something new in the latest releases?

Using the virtualenv method to install MM3 in a fresh Debian 12 VM, I have run into an error while starting the mailman3 service. I cannot figure out what this error means.

IIRC you're one of the folks who creates a new venv and therefore gets upgrades of all prerequisite PyPI packages on upgrade. (Of course this is the recommended RightThing[tm].) If so, seems most likely that it's new in psycopg2.

psycopg2 has been released 3 times since Aug 5, most recently Oct 3, so it seems likely you've upgraded that package.

Try downgrading that package in the venv, to the version in the old venv if you have that available.

...

No log entry in any of the log files in /opt/mailman/mm/var/logs/.

Wouldn't expect them, since imports are early and the most likely relevant loggers (any that are in pyscopg2 itself) wouldn't be set up yet.

I am not upgrading :-) This a completely new VM that has never seen MM3 before. A new Linux install of Debian12. I usually prefer testing first before implementing.

psycopg2 has been released 3 times since Aug 5, most recently Oct 3,

...

so it seems likely you've upgraded that package.

On this test machine, I have psycopg2-binary==2.8.6. The instructions on the documentation <https://docs.mailman3.org/en/latest/install/virtualenv.html#installing-mailm...> say:

pip install wheel mailman psycopg2-binary\<2.9

Try downgrading that package in the venv, to the version in the old

...

venv if you have that available.

There is no other venv on this host. It is not an upgrade, but a new install.

...

No log entry in any of the log files in /opt/mailman/mm/var/logs/.

Wouldn't expect them, since imports are early and the most likely relevant loggers (any that are in pyscopg2 itself) wouldn't be set up yet.

That makes sense.

OK, you're installing a newer version than you ever had before. Bye

Allow me to clarify.

I have whipped up a completely new Debian 12 VM
I am following https://docs.mailman3.org/en/latest/install/virtualenv.html to install MM3. So this is NOT a production machine. My production machines are fine. What I am doing is just to simulate a new install and see if it's seamless. Whatever I am encountering I believe everyone else would also encounter, because I am not deviating from the steps laid out on the official documentation.

Is your database PostgreSQL or some other? If it's not PostgreSQL, see the thread at https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/H...

So my database is PostgreSQL-15:

postgres@debian12:~$ psql
psql (15.3 (Debian 15.3-0+deb12u1))
Type "help" for help.

postgres=#

Below is the output of mailman info which for some reason I forgot to attach in the initial post. Maybe it contains something useful?

...and tested IF mailman user could create a table in the mailman db:

(venv) mailman@debian12:~$ psql -h localhost -U mailman -d mailman -W
Password:
psql (15.3 (Debian 15.3-0+deb12u1))

Type "help" for help.

mailman=> create table xyz(a varchar(100));
CREATE TABLE
mailman=> DROP TABLE xyz;
DROP TABLE
mailman=> \q

But then again mailman info groks!

Looking at what I have:

(venv) mailman@debian12:~$ pip freeze | grep flufl.lock flufl.lock==8.0.2 (venv) mailman@debian12:~$

Now I am lost as to what the issue could be.

Thank you. That solves the problem for sure! But this was detected 4 months ago. When is the permanent solution coming?

It's a PyPI packaging issue https://github.com/pypi/warehouse/issues/10030

It is supposedly fixed. I don't see the issue in my installs. Maybe try reinstalling the flufl.* packages, although IIRC this is a new venv, so that probably won't help.
