Google Nexus 5 :: Monthly Security OTA Update Fails

My Nexus 5 is rooted and in the past OTA updates have always worked just fine. I don't use a custom recovery. However, the November Android security update fails. I was thinking this was because BBS was installed as a system app. After uninstalling that it still doesn't work. The only other thing I use is Adaway, so I reverted back to the original hostfile and also uninstalled BusyBox. Still no dice. Or is it perhaps Marshmallow OTA updates simply won't work if the phone is rooted? How come in the past I've been able to do OTA updates with my phone being rooted?

What can I do to get the update? Does that mean I have to basically lose my user data every month to do an OTA update now and reroot my device
