Проблема с установкой LTSP

На Ubuntu 18.04.1 LTS я попытался установить LTSP в режиме chroot, следуя этому руководству.

Начальная команда

apt install --yes --install-recommends ltsp-server-standalone epoptes

Мой вопрос: как мне исправить эти поврежденные пакеты, а также, если мне удастся установить эту систему, я смогу эмулировать виртуальные машины с помощью тонкого клиента CT-3000 Huawei, на котором не установлена ​​Ubuntu Mate. Я также ищу информацию о том, как установить помощник.
