Why does superset load_examples says "admin user does not exist" even thought one exists?

I found the reason is load_examples requires the exact name admin as the username for the administrator. I changed it to admin1 and it was not recognized.

This should be mentioned in the docs.

I solved it by removing the db and then re-initializing it, as follows:

Delete db:

cd /home/<user>/.superset/
rm -f superset.db

Reinitialize database:

superset db upgrade

Repeat the procedure according with the doc:

export FLASK_APP=superset
superset fab create-admin

And it should work properly:

Username [admin]: admin
User first name [admin]: 
User last name [user]: 
Email [admin@fab.org]: 
Password: 
Repeat for confirmation: 
Recognized Database Authentications.
Admin User admin created.
