Add myself to sudoers file

[CarterCox]

Hello. I'm trying to run this command:

Code: Select all

sudo nano /etc/default/grub

And I get this:

Code: Select all

[sudo] password for xxxx:
xxxx is not in the sudoers file.  This incident will be reported.

How can I solve this?

Thank you very much!

Hi, welcome to the forum.

There is a wiki on that I'm sure, try wiki.debian.org and search for sudo. Also you can search the forum here, there are a lot of good topics to fix almost every problem you will have.

i think they recommend using 'visudo' to edit sudoers file.

You should do some reading at the https://wiki.debian.org/sudo page.

Or just use 'su', see the manual :

Code: Select all

man su

But then again, if you don't know enough basic Linux commands, maybe you
shouldn't be trying to do anything as root, or using sudo yet.

I think, if sudo is installed, there is a manual for it, I don't remember, it has been so long since I used ubuntoo , and my Debian installations do not have it, never installed it.

Code: Select all

man sudo

and

Code: Select all

man visudo

Yes! I did it by typing "su", typinfg the root password and then excecuting commands that way. Everything is done now. Thank you all!
