我尝试在 Ubuntu 上安装 MySQL，但出现以下错误。我尝试了本网站和互联网上的一些解决方案，但似乎都不起作用。
$ sudo apt-get install mysql-server

编辑：我删除了 mysql 包并尝试按照评论中的指示再次安装它。
$ sudo apt-get remove --purge mysql*
$ sudo apt-get purge mysql*
$ sudo apt-get autoremove
$ sudo apt-get autoclean

由于从 ubuntu 18.04 升级到 Ubuntu 20.04 时出现问题，我遇到了同样的错误。我所做的是获取 MariaDB，同时确保在清除 MySQL 时，如果要求删除目录中的数据库，请单击“否”。它不会删除数据库，因此您将拥有旧数据库并且不会丢失数据。
我使用了这些命令：
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade
sudo apt-get install mariadb-server

这为我修复了这个问题（MySQL 8.0-Ubuntu 20.04）
sudo apt-get purge mysql\* libmysql\*
sudo apt autoremove
但该方案“mysql-客户端核心-8.0“不要卸载，所以...
sudo apt --fix-broken install
sudo apt-get --reinstall install mysql-client-core-8.0
sudo apt-get purge mysql\* libmysql\*
sudo apt autoremove
sudo apt update
sudo apt install mysql-server
不再有错误！
