The preinstall check failed. MariaDB cannot be installed. at /usr/local/cpanel/Cpanel/Yum/Install.pm line 470.

Obtained version information from system.
Proceeding with MySQL/MariaDB upgrade despite the following:
Critical: MariaDB enables "strict mode" by default as of version 10.2. Strict mode controls how MariaDB and MySQL handle invalid or missing values in data-change statements such as INSERT or UPDATE. Applications not built with strict mode enabled may cause undesired behavior; please verify applications using MariaDB are compatible before upgrading. More information about strict mode is available here. Normal: When you upgrade from MySQL® to MariaDB 10.2 or later, the mysql_upgrade utility may emit several database table-related errors. The discrepancies in the tables between MySQL and MariaDB versions produce the errors; however, the upgrade process will resolve these issues.
Normal: MariaDB does
notutilize the sys schema. If you upgrade from MySQL 5.7 to MariaDB, you
must manually remove the sys database, because it can cause unnecessary errors during certain check table calls

Any ideas?

Hey there! The Critical and Normal messages you've included aren't the actual error, but are part of the normal warnings we provide users when updating the software on the machine.

Can you read through this guide to see if that resolves your issue with the upgrade?
