You have to kill the anacron.service for apt upgrade to proceed.

So I could not reproduce a hanging upgrade from Debian 12 (bookworm) to Debian 13 (trixie). anacron's jobs from the previous anacron.service are killed before the "apt dist-upgrade" anacron.service is started and the upgrade finished with anacron.service running.

I think systemd-tty-ask-password-agent waiting for a password is the hang which may occur from the daemon-reload [1] in your environment? Is there something different from a default install or permission changes?
