Свежий установленный Ubuntu Server 17 - невозможно найти пакеты и неудовлетворенные зависимости для phpmyadmin

заранее благодарю за любую помощь.

Мой сервер:

Я только что установил Ubuntu Server 17.04 с базовым программным обеспечением и LAMP. (Сначала я попробовал 18, но из-за этой ошибки ( https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1767569 ) я не могу установить его с USB-устройства.

Цель состоит в том, чтобы в моей текущей внутренней сети был локальный веб-сервер. Apache, PHP и MySQL все в порядке.

Я уже настроил свой DNS для указания на веб-сервер, и я получил сайт по умолчанию apache При открытии моего phpinfo я получаю PHP Version 7.0.15-1ubuntu4, так что php7 работает нормально.

Еще не пробовал ftp, но это можно сделать позже.

Проблема:

Все, что мне сейчас нужно, это запустить phpmadmin, потому что сейчас я получаю сообщение об ошибке при открытии / phpmyadmin. Итак, я проверил сервер, и кажется, что phpmyadmin не установлен вместе с LAMP (без папки phpmyadmin в / usr / share /)

Что я пробовал до сих пор:

1. добавил deb http://us.archive.ubuntu.com/ubuntu/ zesty universe multiverse и deb http://us.archive.ubuntu.com/ubuntu/ zesty-updates universe multiverse в список репо
2. Я добавил репозиторий phpmyadmin sudo add-apt-repository ppa:nijel/phpmyadmin
3. У меня apt-get update и apt-get upgrade несколько раз
4. Использовано apt-get install -f
5. Многие другие вещи, которые я не могу вспомнить прямо сейчас, но впоследствии были отменены.

Прямо сейчас я надеваю Не знаю, что еще я могу, но спрашиваю здесь. Я видел, что у многих пользователей уже были проблемы с работой phpmyadmin в Linux с LAMP, но мне кажется, что все эти проблемы были решены с помощью решений, которые я уже пробовал. Я был бы очень признателен за любую помощь здесь. (Если вы спросите: кроме изменений в списке sources.list, о котором я упоминал выше, я не добавил никаких других репозиториев.)
