[Installation] Unable to restart service mysql

Hi i am trying to install erpnext with an ubuntu 16 os via the quick install method, after i download the install.py file i keep getting an error

RUNNING HANDLER [mariadb : restart mysql] **************************************
fatal: [localhost]: FAILED! => {“changed”: false, “msg”: “Unable to restart service mysql: Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.\n”}

NO MORE HOSTS LEFT *************************************************************
to retry, use: --limit @/tmp/.bench/playbooks/site.retry

i really have no idea where to start debugging from, help from here will be deeply appreciated.

Seems mariadb is not running. Please restart the mariadb and then create a new site manually

Fixed the issue by manually uninstalling and reinstalling mariaDB
