Нужна помощь с OpenMediaVault⁠⁠

Приветствую, друзья!
Обращаюсь к сообществу за советом и помощью в настройке OpenMediaVault.
Суть такова: есть домашняя файлопомойка на которой крутиться OMV 7. При ее постройке была задача собрать минисервер из старых комплектух (на данный момент это FX8350 + 8Гб DDR3 + россыпь из пары SSD по 120 Гб и пары HDD на 250 Гб и 1 Тб) и поднять NAS, который может подключаться к WI-FI из коробки. Это важно, т.к. розетки ethernet в комнате нет, как и кабель притащить в неё нет возможности.
Так вот NAS на OMV 7 работает, но хочется большего. Чего, спросите вы? Конечно же miniDLNA и облачного доступа к папкам с фото для неноглядной супруги. miniDLNA работает без проблем - все телевизоры дома его видят, фильмы/сериалы смотрятся без проблем.
И тут начинаются трудности конкретно у меня. А именно настройка Docker. После установки Compose при попытке задать настройки папок в Docker система выдаёт вот такую ошибку:

500 - internal server error

Пр этом, конечно же сам Docker не установлен и не запущен. При попытке его перезапуска система выдаёт ошибку с указанием того, что Docker не установлен.
Попытка его переустановки заканчивается неудачей с ошибкой о потере соединения. Подобные сообщения в разных РУ-форумах или англоязычных пестрят сообщениями о том, что нужно все делать по инструкции с omv-extrass или дают ssl команды, которые в моем случае её помогают - принудительное переустановка либо заканчивается неудачей, либо реакция системы остаётся неизменной.

Все установки я делал как было указано на страничках соответствующих пакетов, в т.ч. omv-extras касательно последовательности установки Compose и настройки Docker.

Ребята, куда смотреть? Чего ему не хватает и откуда это взять?
