Ignore the getpwuid_r() error. That's insignificant.
Please review the instructions. I followed them myself and they produced logs for both ubiquity and dbus, as expected. I suspect you're missing one of the steps if you don't have a ubiquity.log or dbus.log in /var/log. Make sure the first prompt you see after booting from the advanced options screen is "(initramfs)" and not "ubuntu@ubuntu:~$".
