Did this work before? No 

Chrome version: 52.0.2743.116  Channel: stable
OS Version: OS X 10.11.5
Flash Version: Shockwave Flash 22.0 r0

This condition has persisted on my machine ever since I upgraded my Mac OS X from Mavericks (10.9.5) to El Capitan (10.11.5). The OS upgrade may have nothing to do with this issue, but I never had this problem when I was running Mavericks. It seems I need to give access for the key lock file to be read, so it can access it and then perform the update. However, I haven't seen anything on the Chromium forums about how to do this.
