Hi everyone, We all love to watch our favourite Movies, Tv show and Anime online specially when it is free . So I make this tutorial for ubuntu users .Windows and mac users can directly download PopcornTime from the official website  here .
Let’s get started: 
1-Go to  this website : link.
2-Now click on Popcorn-Desktop
3-Search for the .deb links 
4- Download the right version for your system , if it is 32 bits then download the i386.deb and if it 64 bit, download amd64.deb. I am going to add the links directly here : 
*32 bit
*64 bit  
Alternative direct links

*64bit 
5-Wait until the download is done then double click on your file; it will be opened in Ubuntu Software Center.
6- Click on install then enter your password, wait until install is done andthat’s all , popcorntime is installed successfully .
