- Problem: sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
- Cause of this: sudo chown -R $(whoami)  /usr/{lib/node_modules,bin,share}.
- Explaination of the root cause:
     - "chown -R": change file owner and group information. Use the chmod command to change file access permissions such as read, write, and access.
     - "$(whoami)" : Throws the present user
     - "/usr": Only the folders {node_modules,bin,share} will have user rights as tp
     - The "/usr" directory should have "root" as user. 
     
Solution: The Chown cannot be reverted, so re-install is the safest way.
