I typed the passwd command, then input the new password.
~$ sudo passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully
I closed this terminal and open a new one. When I was prompted to input password again, the new password was not accepted, instead the old one was accepted.
$ sudo apt [sudo] password for user: Sorry, try again. [sudo] password for user: apt 1.2.24 (amd64) Usage: apt [options] command ...
What did I do wrong? How can I view my current password?
