ubuntu@arm:~$ sudo passwd root
[sudo] password for ubuntu:

what is the [sudo] password, root password?

How can I login as root? change password for root?

It's ubuntu, by "default" there is no "root" user..

This is the way ubuntu has been since 2006, if you want a root user
you need to enable/create it.

second link if you would have searched google..

http://askubuntu.com/questions/44418/how-to-enable-root-login

[janszyma...@gmail.com]

Hi,

 I did follow the exact link, but the instruction given do not work.

First question:
what would i type after: sudo apt-get update, when asked for password? (tried nothing, root, ... temppwd - nothing works)

login as: ubuntu
ubu...@192.168.7.2's password:

ubuntu@arm:~$ sudo apt-get update
[sudo] password for ubuntu:
Sorry, try again.
[sudo] password for ubuntu:

Second question:
The instruction at the link says:

Enabling

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, rirst execute in a terminal

sudo passwd root

you will prompted for a new Unix password. Write it twice(second for confirmation).

Then execute

sudo passwd -u root 

to unlock the account. This should return

passwd: password expiry information changed

From theory to reality:

ubuntu@arm:~$ sudo passwd root
[sudo] password for ubuntu:

???? what now?

"temppwd" it's been that for over 5 years by default.. You changed something...

from here http://elinux.org/BeagleBoardUbuntu#Trusty_14.04
Can you provide a link to another one, maybe I will have more luck then?

Well, did you reconfigure sshd to allow root access? root over ssh is
a serious security hole and is NOT enabled by default in
openssh-server..

Couple hints here:

[William Hermans]

Sound like someone needs to take their time to learn the OS(es) they're using. Basically this is Debian  / Ubuntu 101, and you should seek information / guidance in those channels. And not bother Robert with such basic questions . . .

This is what I personally think anyway.

"In theory, there is no difference between theory and practice. But, in practice, there is. "

I have modified the file /etc/ssh/sshd_config according to http://askubuntu.com/questions/469143/how-to-enable-ssh-root-access-on-ubuntu-14-04,
but still no root access through ssh.

finally solved

With every Ubuntu version I have used, there is a root user just that a
password is not set for it during install as is the case with other distros.

At no stage do you need to do "useradd root".

login as ubuntu
"sudo su" and give the ubuntu passwd "temppwd"
"passwd root" and set the root password.
Regards
Sid.

Sid, if you've ever used Ubuntu, then you should already know what Robert is saying. Root by default on Ubuntu is disabled. That does not mean there is no root account, it means the root account is DISABLED.

To boot, information about this is all over the web, one simple google search would have provided more than enough information to figure the problem out . . .

Hi William,
I was puzzled by what Robert wrote which I thought could be confusing to a new user.
It was just the wording.

It happens - many a time professionally I have had the shock horror of discovering that what I thought I had  very clearly stated in presentations, documentation and tutorials was totally misinterpreted and enshrined in customers' official documents when they asked me to review them.
Regards
Sid.
