macbook - Trying to install popcorn time 3.2 on Ubuntu 16.04

I am using Ubuntu 16.04 on may mac-book and would like to install popcorn time(the current version is 3.2). However all the packages of popcorn time that I have downloaded either;

1. Do not have an installation file ( so I cannot use sudo ./install )


2. Are not executable and simply do nothing when double clicked,


3. Give me an error "Sorry, this did not work, no file_to_app results to show" when they try open with Ubuntu software installer

EDIT 1; This is the procedure I first used as in a popular post here in askubuntu;

1. Download PopCorn Time.


2. Open a Terminal ( Ctrl + Alt + T ).


3. Enter in your download folder : cd ~/Downloads mkdir $$


4. Extract the downloaded archive tar -xf Popcorn-Time-*.tar.xz -C $$


5. Run cd $$



6. sudo ./install.

   
   
   

   Then when sudo ./install returned no such file, I tried going into the unzipped folder and double clicking the popcorn-time file, that's when I got:

Sorry, this did not work, no file_to_app results to show
