Я перенес на Debian 9 приложение Redmine версии 2.5.0. После копирования всех файлов невозможно выполнить пакетное обновление или установку.

Я установил default-libmysqlclient-dev и затем gem install mysql , но безуспешно.

Обновление пакета выдает этот результат:

 Your Gemfile lists the gem activerecord-jdbcmysql-adapter (>= 0) more than     once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the     version of one of them later.

An error occurred while installing mysql (2.8.1), and Bundler cannot continue.
Make sure that `gem install mysql -v '2.8.1'` succeeds before bundling.
  

Когда я пытаюсь установить пакет, у меня возникает та же ошибка, что и ниже:

 An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
