I tried to install Erpnext through easy installation as per the instructions given in the site (GitHub - frappe/bench: CLI to manage Multi-tenant deployments for Frappe apps) i am getting this error.
It seems your install has mariadb password problem?
This reference may help GitHub - jwrober/erpnext_admin_guide: ERPNext Administrators Guide
Alternatively you can download https://erpnext.com/download
hope this helps
Thanks for your guidens. I have installed ERPnext successfully.
