Unable to Setup Canonical Ubuntu on Rubik Pi

Hello,

I am simply trying to setup my Rubik Pi per the user manual. However, after connecting via the UART terminal (using Windows) the passcode reset fails with ‘authentication token manipulation error’. I’m entering ubuntu as both the username and passcode, and they appear to be accepted. I’ve tried reflashing Ubuntu Desktop with QDL multiple times, but it hasn’t resolved the issue. Alternatively, I’ve also tried setting up Qualcomm Linux but the WiFi won’t setup with ‘An unexpected error occurred while configuring Wi-Fi. Please try again.’ If someone could help me resolve this that would be greatly appreciated. Perhaps less importantly, the QCM6490 USB device depicted in the setup guide doesn’t appear in Device Manager, despite the Micro-USB cable being recognized and the Rubik Pi in EDL mode.

Thanks!
