What could be wrong?
Thanks

Spoke too early.
Do you have the "!root_sudo" option set?

You're welcome.
Do you have an "/etc/pam.d/sudo" file? Can another user use sudo? Any
hint about the reason for the failure in "/var/log/auth.log"?

My bad.
The failed environment is a linux-live environment that I built myself.
When mirroring it to HD, everything works fine. So it's actually the live
environment's problem, not sudo's.
Thanks again for your comprehensive tips, which I'll garter bellow in
case someone else need to troubleshoot:
- Make sure the 'root ALL=(ALL) ALL' line is in /etc/sudoers
% grep ^root /etc/sudoers
root ALL=(ALL) ALL
- should not have the "!root_sudo" option set
$ sudo cat /etc/sudoers | grep root_sudo || echo no
no
Also check,

What could be wrong?
grep root /etc/sudoers
Why should one use "sudo" in addition to being root and thus having all
rights?
I would understand if you add your own user to the sudoers file...but
this way...
Can you tell me the sense behind it? I mean i am really interested in,
because maybe there is something new i can learn about "sudo".
