无法卸载mysql

Question

嗨，我最近在Ubuntu-22.04中启动mysql时遇到了一些问题。当我尝试sudo service mysql start时，会弹出一个错误：

Failed to start mysql.service: Unit mysql.service failed to load properly, please adjust/correct and reload service manager: File exists
See system logs and 'systemctl status mysql.service' for details.

我也尝试过一些来自堆栈溢出和其他论坛的“修复”，但是它们似乎都没有起作用，主要是因为自动删除部分。

有什么想法吗？
