Bug Description

python3-defaults in jammy-proposed switches python3 to be python3.10. This causes barbican's autopkgtests to fail fairly inscrutably:

autopkgtest [09:11:30]: test barbican-daemons: [-----------------------
OK
OK
autopkgtest [09:16:31]: test barbican-daemons: -----------------------]
barbican-daemons FAIL non-zero exit status 22

The 'OK' messages are confirmations that the daemons are started; the actual failing command is the call to curl --fail http://localhost:9311, which connects to apache and then expects a response from barbican-worker via wsgi. The apache log shows output such as:

[Mon Jan 31 21:45:54.931993 2022] [wsgi:error] [pid 15857:tid 139695589144128] [client 127.0.0.1:59380] Timeout when reading response headers from daemon process 'barbican-api': /usr/share/barbican/app.wsgi

The worker log, in turn, shows only:

2022-01-31 21:34:36.092 11378 ERROR oslo.messaging._drivers.impl_rabbit [-] Connection failed: [Errno 111] ECONNREFUSED (retrying in 2.0 seconds): ConnectionRefusedError: [Errno 111] ECONNREFUSED

It's true that the connection is refused, because the autopkgtest doesn't install rabbitmq-server? But this doesn't seem to be a problem when running under python3.9?

If I upgrade to -proposed and then downgrade only python3-defaults, the failure is still reproducible, so this may be caused by by some other package in -proposed besides python3-defaults.

except the autopkgtest log clearly shows only python3-defaults being pulled from -proposed, so it looks like more analysis is needed.

Ok restarting only barbican-worker with python3.10 doesn't fail; it fails only after restarting apache2 with python3.10...

Interestingly, in the "good" pass (migration-reference/0) we have the following testbed packages installed:
libpython3.10 3.10.2-1
libpython3.10-minimal 3.10.2-1
libpython3.10-stdlib 3.10.2-1
libpython3.9 3.9.10-1

Whereas when we pull in python3-defaults from -proposed we end up with:
libpython3.10 3.10.2-1
libpython3.9 3.9.10-1
libpython3.9-minimal 3.9.10-1
libpython3.9-stdlib 3.9.10-1

For some reason the testbed is pulling in some python3.9 bits instead of using python3.10 (that might due to libapache2-mod-wsgi-py3 pulling in both versions of libpython):
