Проблема при установке сервера MySQL

Я пытался установить сервер mysql и рабочую среду mysql с программным центром Ubuntu, но не смог их установить. Затем я использовал командную строку для установки сервера MySQL и выполняю следующий код соответственно:

sudo apt-get update && sudo apt-get upgrade
sudo apt-get install mysql server

Но после последней команды я получил следующую ошибку:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
mysql-server : Depends: mysql-community-server (= 5.6.24-1ubuntu14.10)   but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Как я могу решить эту проблему? Есть ли какой-нибудь простой способ установить MySQL-сервер и MySQL Workbench?
