The minimum python version when installing from source is now python 3.9, as Pyside6 6.7.1 dropped support for python 3.8 (see #780 for more information). On Debian-derivatives distributions, the minimum Python version is now set to 3.8. In practice, because Pyside6 is not packaged for Debian, we use Pyside2 [0], which is why we can relax the python version requirement. In practice, when installing from source on an environment where python3.9 is not the default python, poetry will look for it and use it if available > For various reasons, this Python version might not be compatible with > the python range supported by the project. In this case, Poetry will > try to find one that is and use it. > > [Poetry docs](https://python-poetry.org/docs/managing-environments/) On Ubuntu Focal (20.04) where Python 3.9 is not installed by default, it is possible to install it using the `python3.9` package. Additionally, In version 1.24.3, PyMuPDF changed its package name from `fitz` to `pymupdf` [2], resulting in a breakage on how it is installed in our container. This is now fixed. [0] More information on how Pyside6 packaging affects dangerzone on #221 [1] See [the current status of Pyside6 packaging](https://repology.org/ project/python:pyside6/packages) [2] PyMuPDF changelog: https://pymupdf.readthedocs.io/en/latest/changes.html#change-log
