@NgocThangPham please join me here.

Ngoc Thang Pham

terdon

So. You are working on a rasperryPi right?

Ngoc Thang Pham

yes. I have one, today I installed pinet to make an image OS for Raspi

terdon

OK, but the sudo issue is on the Pi, correct?

Ngoc Thang Pham

No. It's on my computer

terdon

17:25

Then why are you mentioning the Pi?

Is this happening on a live system or have you installed Ubuntu on your computer?

Ngoc Thang Pham

because I it happened after I install pinet

I installed Ubuntu

terdon

OK. So on your computer, not the Pi, you have i) installed Ubuntu normally and ii) installed PiNet. Correct?

Ngoc Thang Pham

Yes

terdon

OK. Now, open a terminal window (Ctrl+Alt+T) and run these commands: i) whoami ii) sudo whoami iii) sudo -k and iv) sudo whoami again.

Here, you can copy/paste this directly into the terminal:

whoami
sudo whoami
sudo -k
sudo whoami

Then copy the output and paste it here.

Ngoc Thang Pham

thang@thang-HP-ProBook-450-G1:~$ whoami
thang
thang@thang-HP-ProBook-450-G1:~$ sudo whoami
root
thang@thang-HP-ProBook-450-G1:~$ sudo -k
thang@thang-HP-ProBook-450-G1:~$ sudo whoami
root

terdon

Damn!

Hmm, what's the output of grep thang /etc/password?

Sorry, I meant this:

grep thang /etc/passwd

Ngoc Thang Pham

thang@thang-HP-ProBook-450-G1:~$ grep thang /etc/passwd
thang:x:1000:1000:thang,,,:/home/thang:/bin/bash

terdon

OK, so no, your user is not root. What is the output of groups?

Ngoc Thang Pham

I think that everything works fine :|

terdon

Yes, but it's very strange that you're not being asked for a password. Something weird is going on.

What is the output of groups ?

Ngoc Thang Pham

Sorry, how can i check my group?

thang@thang-HP-ProBook-450-G1:~$ groups thang
thang : thang adm dialout cdrom sudo audio dip video plugdev games users input lpadmin sambashare pupil teacher

Is it?

terdon

17:33

Yes

I guess the pupil and teacher groups were added by PiNet.

Ngoc Thang Pham

yeah

terdon

This is very strange. I am editing your question to clarify it and to add the information you gave here. Sorry, but I have no idea how this could be happening.

Ngoc Thang Pham

OK. Thanks for your help.

And should i clear group teacher and pupil ?

terdon

@NgocThangPham I don't see how that would be relevant.

Hang on, are there any files in /etc/sudoers.d ?

What's the output of ls /etc/sudoers.d?

@NgocThangPham?

Ngoc Thang Pham

01staff and README

%teacher ALL=NOPASSWD: ALL

in 01staff

terdon

17:42

AAAAAAAAAA

There we go!

OK, let's add that to your question, and I can post an answer.

Ngoc Thang Pham

OK. I will delete that file?

terdon

Either delete it or remove yourself from the teacher group. I don't think PiNet is what you wanted by the way, that's designed for classrooms.

Ngoc Thang Pham

oh ok

Thank you so much. :))

terdon

You're welcome. That was a confusing problem :)

Please remeber to accept my answer so the question can be marked as solved.
