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.
