Почему не запускается Docker?

Question

[Konstantin Zhikhor]

Пытаюсь первый раз развернуть рабочее окружение на  docker. Помогите пожалуйста.

При команде в консоле docker-compose up выводит такой результат с ошибками

docker-compose up

This may mean that the package is missing, has been obsoleted, or
is only available from another source

тут же четко написано
E: Package 'libpng12-dev' has no installation candidate
в вашем репозитории не находится этот пакет.

[Konstantin Zhikhor]

Saboteur, спасибо. А как исправить эту ошибку и первую ошибку которая в самом верху ?

[Saboteur]

первая это не ошибка а warning, его можно игнорировать
Второе - разобраться какой компонент требует libpng12-dev, и выбрать актуальную версию, которая есть в репозитории. Возможо вам подойдет просто указать libpng-dev, без версии.

Answer 1

E: Package 'libpng12-dev' has no installation candidate - нету пакета в репозиториях, которые подключены.

отсюда следует ERROR: Service 'php' failed to build: потому что не установлена. в debian stretch пакет называется libpng-dev .
