**Don't have this user "6d4b9452aef14153" in the database.** 

here is the user list for the database.

MariaDB [(none)]> select host, user, password from mysql.user;
+-----------+------------------+-------------------------------------------+
| host      | user             | password                                  |
+-----------+------------------+-------------------------------------------+

| localhost | debian-sys-maint | *xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx |
| localhost | 1bd3e0294da19198 | *xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx |
+-----------+------------------+-------------------------------------------+

have update the file site_config.json for the db name and password.

But not able to find the file to update the database users name.

Request your support in resolving this issue.

Bench Udpate error

I had exactly the same problem when updating to Version 10. I didn’t know, why it happened, but I knew how to solve it. Probably not the best solution, but it’s working. I changed the Host in the mysql user table from localhost to % and the Host in the mysql db table to %. Please note, if you don’t know exactly what that means, I can not suggest this as a solution. After that changes, flushing the privileges via SQL query and restarting mysql, it worked.

Frappe uses the database name itself as the username for that database, there’s no configuration setting to change only the username

def connect(site=None, db_name=None):
	"""Connect to site database instance.
	:param site: If site is given, calls `frappe.init`.
	:param db_name: Optional. Will use from `site_config.json`."""
	from frappe.database import Database
	if site:
		init(site)
	local.db = Database(user=db_name or local.conf.db_name)
	set_user("Administrator")

Where site_config.json is having the right db name, please find the output of file.

cat site_config.json
{
“db_name”: “1bd3e0294da19198”,
“db_password”: “XXXXXXXXXXXXXXXX”,
“encryption_key”: “XXXXXXXXXXXXXXXXXXXXXXXXX”

Was able to to fix this issue by using the bench setup command. This did entire reconfigure of the site and database.

Thank you all for the support.
