Permission denied when install airflow on ubuntu windows 10

Based on this link https://www.astronomer.io/guides/airflow-wsl/ Installed airflow successfully. When I run the “airflow initdb” cmd its returns an error like below. How can I fix this error?

"Traceback (most recent call last):
  File "/home/user/.local/lib/python3.6/site-packages/airflow/configuration.py", line 632, in mkdir_p

During handling of the above exception, another exception occurred:
