Hello Hugo
​Tried to install python library 

sudo apt-get install python3-renderpm

renderpm

Adding my 2cent here.

I encountered this error after upgrading to Odoo 17.

Traceback (most recent call last):
  File "/opt/odoo/prod/venv/lib/python3.12/site-packages/reportlab/graphics/renderPM.py", line 43, in _getPMBackend
    import rlPyCairo as M
ModuleNotFoundError: No module named 'rlPyCairo'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/opt/odoo/prod/venv/lib/python3.12/site-packages/reportlab/graphics/renderPM.py", line 46, in _getPMBackend
    import _rl_renderPM as M
ModuleNotFoundError: No module named '_rl_renderPM'

bizarrely, I did not encounter the error in my test-environment.

I tried various commands to install/update pycairo / renderpm, to no avail.

I'm running on Ubuntu 20.4

In the end, I noticed my test-environment was installed with Python 3.11, while in production I have 3.12. I create a new venv for production with Python 3.11. That resolved the issue.
