iMac won't stay asleep after 10.12.4 install

Upgraded to 10.12.4 on my iMac and now it won't stay asleep. I put it to sleep and it just wakes up again right after that.

UPDATE: actually, now it won't even go to sleep. I choose "sleep" in the Apple Menu and nothing happens.

Thanks. I ended up doing a combo update and that fixed the problem.
