I have just uninstalled Dremio 3.0 and installed Dremio 3.1 on a Redhat Linux server. When accessing the interface via http://hostname:9047 I am directed to the Welcome to Dremio, please log in page. I do not have a login as I have not yet set up any users. There used to be an initial admin screen in version 3.0 where the first user would be created but I am unable to access that page in version 3.1. I am also not able to add users using the dremio-admin utility. We’re stuck on the login page. I’m wondering if when we removed Dremio 3.0 we left behind some files that Dremio 3.1 sees and therefore is preventing the “first user” page from displaying.
Can you help me understand how to get past this login page?
Did you attempt to upgrade Dremio from 3.0 to 3.1 using the dremio-admin upgrade script docs here, or did you try a “manual” uninstall of 3.0 with the goal of starting fresh?

If you do not want anything from the previous version like reflections/VDS, you can shutdown Dremio, simply delete data folder under /app/dremio and then start Dremio again. This should bring back the
welcome page
If you want to upgrade by rolling back, do you have a copy of /app/dremio/data from the previous install?
