After lots of Googling and investigation, I discovered that the date and time were not set to current, the macbook thought it was year 2000.

You can easily reset the time and date by following the steps below:

Reinstall Os X El Capitan

  • Click Utilities on the menu bar
  • Select Terminal
  • Type date
  • Confirm the date is wrong
  • Type date 062112422016 (example: June 21st 12:42 2016)
  • Exit terminal
  • Click Restart

Once the Date and time are configured you will be able to install OS X.
