@Jorge,

Thanks for the tip! I’ll start using `sudoedit` for a more secure approach.

Actually, the correct way to edit files with sudo is the command `sudoedit file` or `sudo -e file`. It needs the EDITOR environment variable to be set. It runs your favorite editor (nano, kate, neovim, etc.) as an ordinary user but allows you to modify the root file in a secure way. When you use `sudo nano`, you are running the editor as the root user, and that's not good at all.

In reply to Ravi Saive. Yes, I realize this but the install commands as given in the article will not work:

sudo apt install sudo

will generate a sudoers file error. On the other hand, if you are using the root account to install sudo, the leading 'sudo' in the command will generate a "sudo command not found" error.

@dragonmouth,

If you do not have sudo pre-installed on your system, you can still manage to install it or add a user to the sudo group by logging in as the root user.

su -
apt-get update
apt-get install sudo
usermod -aG sudo username
sudo whoami

If you do not have ‘sudo’ pre-installed on your system, how can you use it to install ‘sudo” or to add a user to the sudo group?
