MariaDBを起動しようとしたときに/usr/bin/installのsystemd status=127

私はMariaDBのインストールを10.2にアップグレードしました。
サービスを開始しようとすると失敗したというメッセージが表示され、ステータスを確認すると、次のようなやや奇妙なメッセージが表示されます。

root@server # systemctl status mariadb

そうではありません。ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld (code=exited, status=127) （mariabd.serviceファイルを確認してください。起動前および起動後の手順をrootとして実行するように設定されています。）ステータスコード127を返します。私が知っている限り、これはコマンドが見つからないことを意味します。
ルートとまったく同じコマンドを手動で実行すると、シャットダウン状態がゼロで直接直接動作しました。

まだ走ってmysqld_safe働いてmysqldいます。だから問題ありません。

また、私はDebian 9を実行しています。

アップデート2：

私がしたことは、apt普通ではないことを通過しただけです。したがって、構成を除くすべてのファイルは標準でなければなりません。
