我一直在努力在 Ubuntu 20.04 中安装 mysql 服务器。我做过sudo apt-get install mysql-server之前已经安装了 mariadb。无论我遵循哪篇文章或指南，当我尝试使用或安装时，我总是会收到此消息sudo apt-get install --reinstall mysql-server-8.0：
done!

每次我尝试运行 mysql 时也会收到此消息：
ERROR 2002 (HY000): Can't connect to local MySQL server through socket /var/run/mysqld/mysqld.sock' (2)
我尝试关注许多帖子，例如： 无法让 MYSQL8 在 Ubuntu 20.04 上运行/n https://mariadb.com/kb/en/uninstall-or-delete-mariadb-completely-for-re-installation/
我不知所措，几乎要重新安装 Ubuntu，但仅仅为了让 mysql 正常运行而这样做简直太荒谬了。我怀疑这个问题是 mariadb 留下的某种痕迹，但我已经尝试了所有能找到的方法来消除它，包括 grep dpkg 内容并手动删除。任何帮助都非常感谢。
