I'm attempting to install this on a Lenovo Chromebook Duet. I reach the GUI login screen (which does not ask for a username, and does not allow me to select one).
It asks for a password, but none of the following work:
<blank>
phablet
ubuntu
linux
root
toor
my long pin
my chromebook master account password
my short pin
ubuntu-touch
or even @#$!
I've noticed several other people have asked about this, and it sort of looks like they were disregarded - either told to use the above (which doesn't work), or told to read the readme https://github.com/chromebook-unity/create-usb/blob/main/README.md
None of those appear to work.
Exiting to the command line from the GUI, using ctrl-alt-f2 gives you a command-line login prompt that asks for a username and password, and which I cannot see how to escape from. Entering combinations of the above accounts with or without password also gives no love.
I even tried flashing a fresh copy of the image on new media, in case I had a faulty image. No luck.
I've tried getting into safe mode, but the boot loader on these devices doesn't appear to support it. I've tried holding down f2 during boot, hitting ESC, no dice. The only interfaces available appear to be ones where you must log in, and it will not allow login.
