Both of those updates were never installed so I was unable to uninstall them. However, after doing a "shutdown and update" and then starting the server back up, neither one showed up as an available update for about 10 minutes. While I was typing this reply they showed up again though.
Update history shows that 6 updates failed during the "shutdown and update". KB4019112, KB3092601, KB3122648, KB2957509, KB3179573, KB4019264
