   Who Can Change File’s Permissions?
   First, the root User may be the Default one in Lubuntu.
   So to Check What User you are on:

   whoami

   Again, check What’s your User’s Primary Group Name:

   id -gn

   • You Can Freely Change Permissions over Files/Directories Your User’s Hold.
   • But you need Admin Super User Powers to Change Permissions on Entities he Do Not Hold!
