Comment 3 for bug 1993478

> sshdconfig.txt actually does NOT contain a line with Port 22 (it is commented out)

Why do you mention this? I don't see anything in the log file that mentions Port settings.

Your dpkg log shows:

> Failed to restart ssh.socket: Unit ssh.socket has a bad unit file setting.
> See system logs and 'systemctl status ssh.socket' for details.
> Could not execute systemctl: at /usr/bin/deb-systemd-invoke line 145.
> dpkg: Fehler beim Bearbeiten des Paketes openssh-server (--configure):
> »installiertes post-installation-Skript des Paketes openssh-server«-Unterprozess gab den > Fehlerwert 1 zurück

Can you run this 'systemctl status ssh.socket' command and attach the output?

For developer reference, the logs show this is an upgrade from the jammy version of openssh-server package to 1:9.0p1-1ubuntu7 in kinetic.
