Из логов можно сделать вывод, что порт 80, который нужен Nginx уже занят. Я так подозреваю, что Apache. Поэтому нужно удалить или отключить Apache и поставить Nginx

command not found
ifconfig command not found debian
man: command not found
adduser: command not found

ifconfig command not found debian

Если ifconfig выдаёт ошибку

ifconfig command not found debian

можно либо воспользоваться командой

ip addresses

Либо установить ifconfig

-bash: man: command not found

Чтобы установить справочник man

sudo apt update
sudo apt-get install man-db

bash: adduser: command not found

Обычно для создания и редактирования пользователей нужно иметь довольно много прав.

Часто это делается под root.

Начиная с Debian 10 нас ждёт сюрприз от разработчиков. Если Вы стали root по-старинке, выполнив su без агрументов Ваша системная переменная PATH скорее всего не содержит многих нужных директорий.

Всё потому, что теперь команда su идёт из другого package - util-linux вместо shadow и не обновляет PATH по умолчанию.

Что делать?

Попробуйте

su - root

Подробности здесь

user is not in the sudoers file

Означает, что пользователя user нужно добавить в группу sudo

Выполните

su -
usermod -a -G sudo user

usermod: command not found

Скорее всего эта ошибка появилась у вас в Debian 10 после выполнения su ( Подробности )

Выполните

su -
