update of security question 2015-006

Hi all!

I have a MacMini mid-2011 with 4 GB of RAM.  The operating system is OS X Yosemite 10.10.5.

I tried to download and install the security update 2015-006.  It will not be installed.  I have the following message:

2015 006 security update could not be verified.  It may have been damaged or corrupted during the download.  Click Update to download and verify the update again.  Once the computer is restarted, go to the updates page of the App Store for more information.

Can someone tell me why this keeps happening and what I need to do to fix this?

I tried to get the updated Mini update before I installed El Capitan.

Suggestions please!

Thanks in advance!

Dave
