RPI4 needrestart has no chill

Using a RPI4 to host a couple personal things running in docker containers. I get this message from needrestart whenever I update:

$ needrestart -k
Scanning linux images...                                                                                                                                       

Pending kernel upgrade!

Running kernel version:

  The currently running kernel version is not the expected kernel version 4.19.93-v8+.

Restarting the system to load the new kernel will not be handled automatically, so you should consider rebooting. [Return]

Running Raspian headless and the only pkgs I have installed are docker, docker-compose and, screenfetch (and implicitly their depends (like needrestart))

I have followed directions from this thread by adding the line kernel-kernel8.img but, that left me unbootable and had to be reverted. https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=249021&sid=579c5603f7ba89a8b4e21cbbe2e9f99a

Any suggestions?

Edit: I have been linked here, https://andrei.gherzan.ro/linux/raspbian-rpi4-64/ , seems like it may be a solution…
