Lost password Ubuntu server

I most have typed my password in wrong on initial set up. I can not log in. I am just starting so I have no information to lose.

I have tried urbackupsrv reset-admin-pw

I only get the usage screen.

I tried urbackupsrv reset-admin-pw -p (password)
That did not work either.

What am I doing wrong?

Thanks.

Got it to work. I think I did not use sudo. What worked was
sudo urbackupsrv reset-admin-pw -a admin -p (password)
