What to do if the sudoer is not accepted, even though I followed your tutorial?

Posted August 13, 2021 169 views
Ubuntu 20.04

I created a sudo user as instructed here:

When I test the user like this:
sudouser@my-droplet:~$ su - sudouser

–> I get this result:
sudouser is not in the sudoers file. This incident will be reported.

I would appreciate if the tut would add a link to what to do if this happens.

Hi @0LL13,

It seems like you’ve missed adding the user to the sudo group. Can you please check STEP 3 from the tutorial again and see if it will help you out:

Step 3 — Adding the User to the sudo Group
Use the usermod command to add the user to the sudo group:

usermod -aG sudo sammy

Again, be sure to replace sammy with the username you just added. By default on Ubuntu, all members of the sudo group have full sudo privileges.

  • Thank you for your reply. Is it possible that there is a time lag between creating a sudo user and that user becoming available? It’s now there, I can use the sudouser, and I didn’t repeat any steps.

    • Hi @0LL13,

      There shouldn’t be any. When you execute the commands what they do is, add information to various files which then are checked when you try to use sudo. So basically, as soon as you run them, you should be able to use the user and sudo user.

      Anyway, I’m glad to hear it’s working as expected now.
