Security Update 2019-001 High Sierra has been trying to install itself for WEEKS, over & over. Any advice on how to make it finish?

My computer keeps telling me to update. It tells me that it's almost done, just 13 minutes to go! Then, 13 minutes later, it just stops. The next time I turn the computer on, it tells me I need to update. Restarting doesn't help.

iMac 21.5", macOS 10.13
