I was connecting via VNC to the remote server with the Turnkey Redmine appliance running on it. For some reason, the keyboard registers a "[P" before every character entered, so this seems to have caused the issue. Entering the passwords locally, at the server terminal, fixed this.
May be an issue with Ubuntu server installs and keyboard over VNC. This problem doesn't occur with any other VMs or command lines running on the server (over VNC).
