Debian10「バスター」でのアップデート中にSshdをポート2222にバインド中にエラーが発生しました
更新中の次のエラー出力：
Errors were encountered while processing: openssh-server ssh E: Sub-process /usr/bin/dpkg returned an error code (1) Setting up openssh-server (1:7.9p1-10+deb10u1) ... rescue-ssh.target is a disabled or a static unit, not starting it.

次に、_$ Sudo dpkg --audit_は次の出力を返しました。
The following packages have been unpacked but not yet configured. They must be configured using dpkg --configure or the configure menu option in dselect for them to work: ssh secure Shell client and server (metapackage)
The following packages are only half configured, probably due to problems configuring them the first time. The configuration should be retried using dpkg --configure <package> or the configure menu option in dselect: openssh-server secure Shell (SSH) server, for secure access from remote
また、ポート22が_/etc/ssh/sshd_config_で2222に変更されていることを考慮してください。
何か案は？
次のように進めることができます：
$ Sudo systemctl disable sshd $ Sudo systemctl daemon-reload $ Sudo dpkg --configure openssh-server
そしてついに
$ systemctl enable sshd
