Change Dremio Admin Name Linux?

Is there a way to reset or change Dremio Admin name on Linux?

Are you referring to the Admin user in the Dremio Web UI? If so, why don’t you just create another Admin user and delete the other one?

Admin user in Web UI

There you go! Easy fix then. I don’t think Dremio has the concept of a centralised (root) Admin account (Web UI) . I would just create a new one and delete the other one. Backup any datasets sitting in the home space of the user you will delete so you can recreate them in the new user home space
