OK, ran across this today, and there are a few ways to fix it.  The most time-consuming way (but seems to me to be the least invasive) is to remove 976569 and 976570, install 974417 (reboot), and then re-install 976569 and 976570.  I do not know what it is about those two updates that seems to cause the failure, but since I’m building images I don’t really care either – the workaround “fixes” it well enough for me.
