Я создаю неуправляемую установку с помощью preseed для Ubuntu Desktop 18.04.4, и я хочу установить openssh-server (openssh-sftp-server для рабочего стола), делая его фактически возможным ssh после завершения установки.

Я пробовал использовать такие команды, как: pkgsel/include, ubiquity/success_command и preseed/late_command безрезультатно.

Preseed не устанавливает программное обеспечение и не обновляет пакеты.
