I have some Ruby on Rails projects on my computer running Ruby 2.5.1. I previously had MySQL 5.7 installed on my system (MariaDB). After upgrading to MySQL 8, these Ruby on Rails projects using Ruby 2.5.1 stopped working. The error appears to be some Ubuntu configuration or libraries that were used with MariaDB and are no longer needed. I've attached a few lines of the error (there are about 10,000 lines of error):

Edited error after upgrade mysql2 gem to '0.5.4'

I have other Ruby on Rails projects with Ruby 3 that work perfectly. This only happens with Ruby 2.5.1.
