Dear folks,

Greetings from Monirul this side, 

During an upgrade of Koha to version 24.05.03-1, the process failed due to a
database access error. The upgrade script was unable to connect to the
MySQL/MariaDB database, suggesting a potential issue with database permissions
or configuration.

Steps to Reproduce:

Attempt to upgrade Koha-common package to version 24.05.03-1
Run sudo apt-get install mariadb-server
Confirm the installation/upgrade process

Observed Behavior:

The upgrade process fails during the database schema upgrade step
An error message indicates that access is denied for the Koha database user

Error Message:
"DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: DBI
connect('database=koha_monirul;host=localhost;port=3306','koha_monirul',...)
failed: Access denied for user 'koha_monirul'@'localhost' (using password: YES)
at /usr/share/koha/lib/Koha/Database.pm line 91. at

Operating System: Ubuntu (likely 24.04 based on package versions)
