MySQL 安装损坏，无法安装或卸载

我安装了 MySQL，但安装过程中我的电脑崩溃了，Linux 终端死机了，因此取消了操作……现在，当我尝试安装它时，出现了这个错误

Setting up mysql-server-8.0 (8.0.25-0ubuntu0.20.04.1) ...
Failed to stop mysql.service: Unit mysql.service not loaded.

 installed mysql-server-8.0 package post-installation script subprocess returned error exit status 127
Errors were encountered while processing:

E: Sub-process /usr/bin/dpkg returned an error code (1)

我尝试过做一些步骤

1st Try:
sudo apt-get clean
sudo apt-get purge mysql*
sudo apt-get update
sudo apt-get install -f
sudo apt-get install mysql-server-5.7
sudo apt-get dist-upgrade

2nd Try:
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade

但无论我怎么尝试仍然无法工作，如果有人能帮助我或者给我指明正确的方向，那将是一个巨大的帮助...我已经试着解决这个问题两个小时了，真的没有主意了...

编辑：此外，我无法使用升级服务器，sudo apt-get upgrade因为我收到同样的错误

要重新安装软件包，您可以使用

sudo apt-get install mysql-server-5.7 --reinstall

如果重新配置包时出现问题，您可以使用

sudo dpkg-reconfigure mysql-server-5.7

还要检查 var/log/mysql 中的错误日志，其中可能包含有关 mysql 无法正常工作的线索
