Debian9 下安装MariaDB10 mysql换各种方式安装不上去 mariadb-server : Depends: mariadb-server-10.X

Debian9系统下，安装MariaDB10 换以下各种方式安装不上去，网上搜索的1~5中的方式都有人解决成功过，具体方式贴在下面：

报错：

mariadb-server : Depends: mariadb-server-10.4 (>= 1:10.4.7+maria~stretch) but it is not going to be installed

E: Unable to correct problems, you have held broken packages.

解决方式：

1. 刚开始只是更新apt后安装，执行命令和报错具体如下所示

sudo apt-get update
sudo apt-get install mariadb-server

root@instance-tbbjrcnc:/etc/apt/sources.list.d# sudo apt-get install mariadb-server

The following information may help to resolve the situation:

 mariadb-server : Depends: mariadb-server-10.4 (>= 1:10.4.7+maria~stretch) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

2. 换配置mariadb版本 10.1版本：

sudo apt-get install software-properties-common dirmngr
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirrors.dotsrc.org/mariadb/repo/10.1/debian stretch main'

sudo apt-get update
sudo apt-get install mariadb-server

3. 换配置mariadb版本 10.2

sudo apt-get install software-properties-common dirmngr
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirrors.dotsrc.org/mariadb/repo/10.2/debian stretch main'

sudo apt-get update
sudo apt-get install mariadb-server

3. 换配置mariadb版本 10.3

sudo apt-get install software-properties-common dirmngr
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirrors.dotsrc.org/mariadb/repo/10.3/debian stretch main'

sudo apt-get update
sudo apt-get install mariadb-server

4. 换配置mariadb版本 10.4

sudo apt-get install software-properties-common dirmngr
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xF1656F24C74CD1D8
sudo add-apt-repository 'deb [arch=amd64,i386,ppc64el] http://mirrors.dotsrc.org/mariadb/repo/10.4/debian stretch main'

sudo apt-get update
sudo apt-get install mariadb-server

以上方式都是官网查到，我都试了不行。

5. 以下方式试了也不行

apt-get install aptitude 
aptitude update
aptitude upgrade
aptitude dist-upgrade 
aptitude install mariadb-server

6. 最终解决方式:

aptitude install  mariadb-server

当你运行上边的命令，会出现：

y/n/q

当你选择n的时候，它会显示另一个解决方法，我当时直接y并没有安装成功，

第二次我选n，它提供另一种解决方式，问题解决。
