Question

After logging into ssh, I got this message:

\'Username\' is not in the sudoers file. This incident will be reported.

How can I r

Answer 1

Both the above answers are correct as far as they go but it is easier to add your user to the sudo group in debian based systems (Ubuntu, kbuntu, debian, etc) and the wheel group under RedHat based systems (RedHat, Fedora, CentOS, etc)

usermod -a -G sudo user
or
usermod -a -G wheel user 

Answer 2

This is a very common error for the beginners. The error occurs because we are trying to access/update something with super privileges from the user instead of root -user.

Hence, to solve this,we need to make changes in the sudoers file where the root user has been given the privileges. So, switch to root user,run the following command

# vi /etc/sudoers

The editor would open the file, now scroll down to the bottom where you will see a line

#User privilege specification

root     ALL=(ALL:ALL) ALL

username ALL=(ALL:ALL) ALL

As you can see, I have just added my username with all permissions.

Save the file, and exit. Switch back to the user and start using sudo commands with ease.

Answer 3

Open file

sudo nano /etc/sudoers

Then add the user below admin user like below syntax.

user_name ALL=(ALL)  ALL

Answer 4

You should use visudo to edit /etc/sudoers file.

Just run sudo visudo -f /etc/sudoers

and add your username with correct syntax and access rights. You can find more in man sudoers
