I got this error.
Solution (no need to re-download, nothing wrong with the installation file):
1. turn off network connection,e.g. wifi (top right installation nav bar/menu) or network card (right click network icon in bottom guest window) or whatever to disconnect your network e.g. cut the cable etc
2. change date backward from terminal in the installation, top sub-menu terminal. e.g date 0512122316 for May 12 12:23 2016. If you did not disconnect the network in step 1, the date will immediately back to current date right after you close the terminal. The date will automatically updated when installation success and connected to network.
It's work for me
Thanks to @MaLd0n for the great works
I plan to native install to my Asus Z8NA-D6 Dual Xeon L5640 12 cores 24 thread, is it possible?
