我不是要从apt-get安装自己的软件包。而且问题每月都会出现并消失几次

当我尝试安装较旧的安装程序mysql-apt-config_0.8.6-1_all.deb时，在Debian 9.4 Stretch上出现以下错误
W：GPG错误：http://repo.mysql.com/apt/debian Stretch InRelease：以下签名无效：EXPKEYSIG 8C718D3B5072E1F5 MySQL版本工程 E：存储库“ http://repo.mysql.com/apt/debian Stretch InRelease”未签名。 N：无法安全地从这样的存储库更新，因此默认情况下被禁用。 N：有关存储库创建和用户配置的详细信息，请参见apt-secure（8）联机帮助页。
但是我使用apt-get和gdebi-core来安装mysql而不是mariadb。我猜这个过程将类似于Ubuntu。如果您愿意使用该脚本，则以下内容可能会有所帮助。
这将为您提供截至2019年的具有最新签名密钥的最新mysql软件包。如果您发现签名无效或已过期，则始终可以从这里https://dev.mysql.com/downloads/mysql/）获取最新的安装程序。
wget https://dev.mysql.com/get/mysql-apt-config_0.8.12-1_all.deb
apt-get install gdebi-core
gdebi mysql-apt-config_0.8.12-1_all.deb
********************************在向导中************** ****************************************
配置mysql-apt-config
您要配置哪个MySQL产品？
选择MySQL服务器和群集（当前选择：mysql-5.7） 标签 选择确定
然后选择“确定”并按Enter键
配置mysql-apt-config
您希望获得哪个服务器版本？
选择mysql 5.7
然后选择“确定”并按Enter键
您始终可以通过直接编辑/etc/apt/sources.list.d/mysql.list来源列表来查看选择手册。 安装MySQL Server
apt update
apt install mysql-server
systemctl status mysql
应该显示类似的内容
systemctl状态mysql ●mysql.service-MySQL社区服务器 已加载：已加载（/lib/systemd/system/mysql.service；已启用；供应商预设：已启用） 活动：自Sun 2019-02-24 08:57:51 UTC起活动（运行）; 10分钟前 主PID：14787（mysqld） CGroup：/system.slice/mysql.service 14─14787/ usr / sbin / mysqld --daemonize --pid-file = / var / run / mysqld / mysqld.pid

这应该可以解决您的mysql安装问题。
