Oracle Database Discussions

I am using fedora 20 64bit. I have downloaded oracle 12c for linux from oracle website, then I have followed all the steps in the oracle documentation for installing oracle 12c in fedora20. I have done everything installed all the required packages mentioned there. After that I run the installer and did every step as mentioned in the website but during installation some error occurs, I also have seen the log file but didn't understood why the errors are occurring, I am giving the error report and attaching the log report. Please can anyone help me to install the product. I am t rying to install it into my dell laptop.
