Hi I have Ubuntu Server 14.04.2 LTS installed and when I use sudo with my regular username it requests my username password instead of the root password. Is this normal? If not, how do I set it up to ask for the root password?
That is normal. User which you are logged in as is in the group
Also, if you want, you can create
root user - but it is not recommended. That will make a known target for crackers to attack your system.
To actually enable
root logins first you have to set a password for the
root account and then unlock the locked
root account. If you don't set a password for the
root account the
passwd command will return
passwd: unlocking the password would result in a passwordless account.
So, first execute in a terminal
sudo passwd root
you will prompted for a new Unix password. Write it twice(second for confirmation).
sudo passwd -u root
to unlock the account. This should return
passwd: password expiry information changed
