Rails 4: Why assets are not working under development on Ubuntu 16.04

I have a project cloned from a repo and on my mac is working. But on the Ubuntu 16.04 machine no. The assets are broken and seem there are no errors. The same project works on a Mac machine from same repo. I need to understand how to fix this and what could be the cause of Ubuntu to give this problem. In the console no errors. Just the assets are not working.
