Mysql 8 安装问题

Question

我正在尝试升级到 mysql 8，但得到以下信息。我不知道从这里该做什么。我没有看到太多关于要调查什么错误的信息。它说它已安装，但当我尝试启动它时，我遇到了相同的错误。

mysql-server is already the newest version (8.0.15-1ubuntu18.04).
The following packages were automatically installed and are no longer required:
  libcgi-fast-perl libcgi-pm-perl libevent-core-2.1-6 libfcgi-perl libhtml-template-perl
Use 'apt autoremove' to remove them.
