When i set up armbian after first boot, when the screen went to the bottom line, the resolution would not allow me to see the bottom line, so when it asked me to set a password for the user, i hit return - it allowed me to enter a blank password, but now when i try to config for sudo, it does not accept a blank password. If i reinstall the same thing will happen. is there anyway to change or set the admin password from a blank password? 1234 does not work or the new password i set up for root also does not work.
