Hi,
As others have already mentioned, Debian does not change the host keys by
default.
The package "cloud-init" can regenerate SSH host keys on every reboot. I'm not
sure whether cloud-init is installed on your system, but if it is, you can
disable this behavior by creating a file such as
/etc/cloud/cloud.cfg.d/01_sshkeys.cfg with the following content:
ssh_deletekeys: false
Best regards,
Klaus.
