I have a Flask/UWSGI application running on my home server. A recent Ubuntu upgrade deleted Python 3.10 and installed Python 3.12 instead. I've made a new venv and installed the application, but it no longer runs. In the UWSGI log it says:
ModuleNotFoundError: No module named 'wsgi'
My application is called sieve and the working directory is /usr/share/sieve. I'm using a ini file, /usr/share/sieve/sieve.ini, which looks like this:
[uwsgi]
module = wsgi
callable = app
master = true
processes = 5
socket = /usr/share/sieve/sieve.sock
chmod-socket = 660
vacuum = true
die-on-term = true
logto = /usr/share/sieve/sieve.log
logfile-chown = jon:www-data
log-date = [%%Y-%%m-%%d %%H:%%M:%%S]
I've also tried module=sieve.wsgi and module=wsgi:app as suggested elsewhere.
The application is in a sieve subdirectory and /usr/share/sieve/sieve/wsgi.py looks like this:
#!/usr/bin/env python
from run_app import app
if __name__ == '__main__':
app.run(debug=True)
The service definition includes these lines:
WorkingDirectory=/usr/share/sieve
Environment="PATH=$PATH:/usr/share/sieve/venv/bin"
ExecStart=/usr/share/sieve/venv/bin/uwsgi --ini sieve.ini --enable-threads
I'm not sure what has changed since it was last working, but looking further up the log, this setup worked fine:

The current version does not work (with the same site code and config).

Why has my application stopped working and what to I need to do to make UWSGI find the module again?
