This issue occurs when your user account is not in the sudoers group. Here are the solutions:

Solution 1: Add user to sudo group

# Login as root or another admin user
su -
# Add your user to the sudo group
usermod -aG sudo yourusername
# Log out and log back in for changes to take effect

Solution 2: Edit sudoers file directly

# Use visudo to safely edit sudoers
visudo
# Add this line at the end:
yourusername ALL=(ALL:ALL) ALL

Important: Never edit /etc/sudoers directly. Always use visudo to prevent syntax errors.
