在Ubuntu18.10上安装MySQL 8失败

Question

我已经从mysql-apt-config安装了C1包，安装的包是mysql-apt-config_0.8.13-1_all.deb。

在运行命令Mysql安装问题时，在执行sudo apt install mysql-server的解决方案时，我将收到以下响应

系统正在尝试安装mysql-server-5.7 & mysql-client-5.7而不是MySQL 8。

我该怎么办才能解决这个问题呢？

我正在使用Ubuntu 18.10 (宇宙)

尝试aptitude show mysql-server (假定配置了第三方存储库并运行了apt-get update )。在我与Nginx类似的例子中(现在MySQL是从.deb安装的)，我注意到在输出顶部有正确的新版本，而“由”(在我看来就像“要安装”一样)提供的包仍然显示了更老的版本。继续安装，我收到了我正在寻找的最新版本。不幸的是，我现在无法在干净的操作系统上检查这个。
