After starting the virtualbox console by clicking "Start" in the Oracle VM Virtualbox Manager, and then entering "notebook()" once I've logged into sage via the username/pw "sage"/"sage", I am then able to open my browser to localhost:8000.
However, it then prompts me to sign in via a username and password.
I've tried using sage/sage, my local machine username/password, my google username/password, all to no avail. Each time it says that "Username is not in the system".
Any ideas?
