sudo apt install python3-flask-apscheduler WANTED

[clemefr]

We need to install globally flask-APScheduler

flask-APScheduler is available from https://pypi.org/ (with sudo pip3 install)

The reason why the pip install command doesn’t work in Ubuntu >23.04 is down to an intentional shift in policy (also taken in Ubuntu’s upstream, Debian) to avoid conflicts between the Python package manager and Ubuntu’s underlying APT.
Basically, you can’t run pip install outside a virtual environment in Ubuntu 23.04. If you try to, you get a “externally managed environment” error

As many have already did (python3-flask-sqlalchemy, python3-flask-mail, etc.. ), python3-flask-apscheduler is still missing for installation with sudo apt install

You still can use virtualenvs. pipx, poetry, etc. all work as usual.

The install doesn't even work under virtualenvs any more.
