How to Sudo

Here’s how to install sudo:

  1. Become root: You’ll need root privileges to install software. Use the su command to switch to the root user:
su -

Enter the root password when prompted.

  1. Install sudo: Once you’re logged in as root, use the apt package manager to install sudo:
apt update 
apt install sudo
  1. Add user to sudo group (again): After installing sudo, repeat the command to add your user to the sudo group (since the previous attempt likely failed):
usermod -aG sudo <username>

Log out and back in: To ensure the changes take effect, log out of your current user session and log back in.
