I can't reproduce this. I created an Incus container using testing, created a test user with a password, applied the configuration you gave above, tested that I could SSH to it, and then upgraded it to unstable. Everything still worked fine. I suggest temporarily adding "LogLevel DEBUG3" to your configuration, restarting sshd, trying again, and sending the resulting debug log to this bug report (e.g. `journalctl --unit=ssh.service --since='5 minutes ago'` if you're booting with systemd, or otherwise look around in your system logs). The resulting log may have things you consider sensitive such as IP addresses, user names, and public keys, so feel free to redact anything like that; and you should undo that LogLevel change after gathering this information, since it can violate user privacy.
