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

Question 1

Заранее спасибо за любую помощь.

& nbsp;

Мой сервер:

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

Цель: иметь локальный веб-сервер в моей текущей интрасети. Apache, PHP и MySQL работают нормально.

Я уже настроил свой DNS, чтобы указать на веб-сервер, и я получаю сайт по умолчанию apache. phpinfo Я получаю PHP Version 7.0.15-1ubuntu4, поэтому php7 работает нормально.

Еще не пробовал ftp, но это можно сделать позже.

& nbsp;

Мой сервер:

Все, что мне нужно сейчас, это запустить phpmadmin, потому что прямо сейчас я получаю сообщение об ошибке при открытии / phpmyadmin. Итак, я проверил сервер и, похоже, phpmyadmin isn 't установлен вместе с LAMP (нет папки phpmyadmin в / usr / share /)

& nbsp;

То, что я пробовал до сих пор:

Я добавлено 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. Я добавил репозиторий phpmyadmin sudo add-apt-repository ppa:nijel/phpmyadmin. Я apt-get update и apt-get upgrade несколько раз. Используется apt-get install -f. Многое другое, что я не помню. r теперь, но были возвращены впоследствии.

Теперь, когда я выдаю команду apt-get install phpmyadmin php php-mbstring php-xml libjs-sphinxdoc dbconfig-mysql php-php-gettext php-phpseclib php-curl php-gd php-bz2 php-zip php-tcpdf, я получаю следующие ошибки:

Сейчас я не знаю, что еще могу, но спрашиваю здесь. Я видел, что у многих пользователей были проблемы с получением работы phpmyadmin в Linux с LAMP, но мне кажется, что все эти проблемы были решены с помощью решений, которые я уже пробовал. Я бы очень признателен за любую помощь здесь. (Если вы спросите: помимо изменений в sources.list, о которых я упомянул выше, я не добавил никаких других репозиториев.)

Question 2

Хорошо,
