I have a computer running Debian Jessie, and need to recover my root password. I've been following the instructions on this question, but have run into a snag. After GRUB loads and I've appended single init=/bin/bash
to the appropriate line and rebooted, the system appears to lock up - or at least does not accept any input from my keyboard. I don't appear to be at a proper command prompt, so I'm guessing the former is true.
What can I do to troubleshoot this problem?
