User could not be registered in Authentication

The fact it is giving you the option to download a firmware version that you already have on an inactive partition may suggest you've clicked update previously and it hasn't "gone through". I'm reaching here; but first thing I'd do is manually boot into the inactive (18.5.3) partition and then try again. Make sure you take a backup first, there is always a chance things will go up in smoke.

Hi Ryan,

Thanks for your reply.

I had tried it too, but got the same result.

It's very strange...

Only other thing I can think is the user already exists, but I'm guessing you've already checked that. Can you create any user at all, maybe without underscore_?

Hi Ryan,

Yes, I had checked it already and I could not create any user.
