我需要使用以下命令清除 MYSQL 安装：
sudo apt remove --purge mysql-server
sudo apt purge mysql-server
sudo apt autoremove
sudo apt autoclean
sudo apt remove dbconfig-mysql
一切似乎都顺利。
尝试重新安装更新文件列表后出现以下错误：
Setting up mysql-server-8.0 (8.0.30-0ubuntu0.22.04.1) ...
Renaming removed key_buffer and myisam-recover options (if present)
ERROR: Unable to start MySQL server:
mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 2 - No such file or directory)
mysqld: [ERROR] Stopped processing the 'includedir' directive in file /etc/mysql/my.cnf at l
ine 20.
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!
Please take a look at https://wiki.debian.org/Teams/MySQL/FAQ for tips on fixing common upgr
ade issues.
Once the problem is resolved, run apt-get --fix-broken install to retry.

我查看了 wiki 链接，没有帮助。我看到三年前在这里发布的一篇类似帖子，按照推荐尝试了“apt install -f”，但还是没有帮助。
答案1
在尝试删除 mysql 之前，请确保已使用将其关闭sudo systemctl stop mysql，然后尝试再次发出命令。
停止 MySQL 服务后，您可以运行systemctl status mysql以确保它已关闭。
如果它有效的话请告诉我。
[其他解决方案]
根据错误消息创建目录。
sudo mkdir -p /etc/mysql/conf.d/
创建一个新mysql.cnf文件并写入[mysql]其中。
echo "[mysql]" | sudo tee /etc/mysql/conf.d/mysql.cnf
并重新配置软件包。
sudo dpkg --configure -a
