Unable to build lxml for Odoo 15 on Debian 12

dependencies debian lxml v15 pip

I'm trying to install Odoo on a Debian 12 server in order to recover someone else's website that is built with Odoo 15.

As I don't know Odoo, I follow a tutorial whose link I'm not allowed to paste here, it's for odoo 16 but I replace all occurences with odoo 15.

`pip3 install -r odoo15/requirements.txt` could not build wheels for 4 packages, which I install manually (while in virtual environment):

pip3 install gevent greenlet lxml reportlab

I comment the corresponding lines in `requirements.txt` then re-run the first pip3 command.

After this, I try to run Odoo:

odoo15/odoo-bin

I run into this error: `SystemError: initialization of _psycopg raised unreported exception` which I solve with:

pip3 uninstall psycopg2
pip3 install psycopg2-binary

Then, the beginning of trouble with lxml:

```

Traceback (most recent call last):

ImportError: lxml.html.clean module is now a separate project lxml_html_clean.

Install lxml[html_clean] or lxml_html_clean directly.

```

I read on another post of this forum that I can solve this by installing an older version of lxml:

pip3 uninstall lxml
pip3 install lxml==4.8.0

But the installation fails, and this time, my research hasn't yielded a workaround. Here is the big (and final) traceback:

```
