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.

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
***@192.168.7.2's password:

***@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:

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

???? what now?

Regards,

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.

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.

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:

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.
