Actual Behaviour:

But I see this without admin password:

And if I try go by admin panel URL then I see this:

I use Orange PI One and Armbian Bionic OS.

Debug Token:

I can't give you debug code. You can see reason on screen:(

The Pi-hole installation did not appear to complete. Run the verbose version of the installer and the last step will tell you where the installer stopped:

curl -sSL https://install.pi-hole.net | sudo bash -x

[findkmp]

By this command I got installation completed successfully from first attempt and now I know password!
Thank you!
