我尝试在我的 ubuntu 上安装 mysql 和 mysql 社区版本。但一直失败。这似乎是环境问题，因为相同的安装命令在云 ubuntu VM 上运行。但是，无法找出问题所在，在 google 和这个论坛上也检查了一些现有问题。请建议在哪里检查正确的日志以及可能的修复方法。

如果我尝试社区安装，也会遇到类似的错误。还尝试下载和安装 deb 包，但都失败了。还尝试了 mysql 8 和 5 版本。
还清除了现有的 mysql 安装并删除了 mysql 文件：sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*
在评论中询问 journalctl -xe log.. （没有生成日志！）：
