我正在尝试将5.5.62安装升级到5.7，但是当我尝试“ sudo apt-get install mysql-server”时，它会继续尝试再次安装5.5.62。
这就是我的工作
wget https://dev.mysql.com/get/mysql-apt-config_0.8.13-1_all.deb
sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb
sudo apt-get update
sudo apt-get install mysql-server
但是我收到一条消息

因此，即使我在运行sudo dpkg -i mysql-apt-config_0.8.13-1_all.deb时指定了5.7，它仍然会继续尝试安装5.5.62。
