Hello @suman_kumar_dey,
Execution of “kaltura-db-config.sh” will fail, if there exists Kaltura’s databases, users, procedures in your MySQL server.
So that, you should remove them before re-configuration of the Kaltura CE.
For example, you can remove them and unlock base configurations by using the following commands:
# /opt/kaltura/bin/kaltura-drop-dwh.sh YOUR-MYSQL-ROOT-PASSWORD
# /opt/kaltura/bin/kaltura-drop-db.sh
# rm /opt/kaltura/app/base-config.lock
Regards
