Why This Happens

The issue arises because MariaDB does not support data directories created by MySQL 8.0. MySQL and MariaDB, while closely related, have diverged in certain functionalities, leading to incompatibilities especially concerning their data formats.

The Solution: Steps to Resolve the Error

To successfully install MariaDB and troubleshoot the error, follow these organized steps:

1. Backup Important Data

Before making changes, always ensure that you back up any important data stored in the MySQL directories. If you have databases that you want to keep, use the mysqldump command to export your data.

2. Remove Existing MySQL Data Directory

You will need to remove the MySQL data directory and any relevant configuration files that may conflict with your MariaDB installation. To do this, execute the following command in your terminal:
