我尝试使用 Ubuntu 软件中心安装 mysql 服务器和 mysql 工作台，但无法安装它们。然后我使用命令行安装 mysql 服务器并分别运行以下代码：
sudo apt-get update && sudo apt-get upgrade
sudo apt-get install mysql server
但是，我在执行最后一条命令后收到以下错误：
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.
我该如何解决这个问题？有没有简单的方法来安装 mysql 服务器和 mysql 工作台？
