Error when running airflow webserver on WSL Ubuntu

I am new to airflow, I have installed Ubuntu and enabled WSL version 1 on my windows 10 machine, I then made sure I had python 3.10.6 on the Ubuntu instance, and I installed pip, after that I installed apache-airflow 2.4.3
everything seemed to be fine, I used aiflow db init, and created an admin username, however, when I tried to access the webserver with this command airflow webserver -p 8080 nothing loads in my localhost, so I thought a process has priority on 8080, I changed the port in airflow.cfg file and it worked fine, I tried the same command with the new port, the webserver loaded and I was able to login airflow starts fine

However I am greeted with infinite errors and an unresponsive DAGs page, I can't click on anything in the DAGs page, and the terminal is full of errors as below, most of them show this error, sqlite3.OperationalError: disk I/O error

another issue, which I think is related, but I wanted to be sure, I tried closing and killing the process, and tried a different command airflow webserver -D and airflow scheduler -D they both run successfully and I saw the airflow process start messages, no errors showed up, however when I accessed the port the message told me the webserver was listening at, the page didn't even load and I got a This site can’t be reached localhost refused to connect. error

Solution

  • I fixed the issue by updating WSL from 1 to WSL 2, removing Ubuntu and installing it again from Windows App Store and basically doing all the same steps again. and it worked.
