You might be used to a
sudo based workflow. Some systems, like Ubuntu, ship with it enabled and configured by default. Others, like Debian, do not.
Here is how get
sudo working on a system that does not have it.
First, switch to root:
Next, install the
sudo package using
rpm or other package manager. On
apt based systems do:
apt update apt install sudo
Next you will need to add yourself to the sudoers group:
usermod -aG sudo username
Now completely log out, and log back in for this to take effect.
You should now be able to use
sudo with your account.
You will need to add any other users who need
sudo access to the
sudo group as shown above.
