I tried removing my administrator account's password. Now that there is no password set for it, I cannot put a new one nor do any actions which needs administrator privileges.
I tried different fixes found on askubuntu, including resetting of password using recovery mode. However my problem is that when I'm on the part where the console asks for password, I cannot type anything, thus I can only send a blank respond.
Then it's unchanged. I also experience this kind of problem that I'm unable to enter password on consoles like when I tried on the free Debian server I got (just putting it up an example just in case you can help me to this problem).
Thank you very much! And I'll appreciate immediate help. More power to Ubuntu.
