Apache2 устанавливают попытку на Lubuntu 18.04: с Ошибками встретились при обработке: apache2

При попытке установить apache2 на моей машине я получаю это:

After this operation, 534 kB of additional disk space will be used.

Кто-либо знает проблему? Я также попробовал:

/etc/init.d/apache2 stop
sudo apt-get purge apache2*
sudo dpkg --configure -a
sudo apt-get install -f
sudo apt install apache2

но это регистрирует почти ту же проблему:
