I'm running a Zen 2017 virtual appliance (on vmware if that's useful to know); Zen 2017 Update 2a is not showing up in System Updates when I hit "Check for Updates". Update 1 appeared, so I thought maybe it wanted me to install that first which I did a few days ago, but still no Update 2a.

I know there's a manual install procedure, but it's kind of a pain and I'm wondering if the reason Update 2a doesn't show up is because I shouldn't be installing it yet (like there's some issue with installing it on the appliance version of Zen?).
