Just to clarify - the updates to .140 did complete successfully, it's just that the status reported gets hung at some point. So it's a UI issue, doesn't block the update.
Mine appeared to be sitting and not changing for quite a while, at least maybe 20 minutes on the hub where it hung showing a percentage verifying the download. But I wasn't timing it so I just don't know. In all cases as soon as I refresh the page it showed the update as installed and everything was fine.
See, mine is actually kicking out. Like it aborts but then when I try to do it again I simply get the message that the hub is rebooting and never does. I also discovered that during that time random things are non functional. This has happened a few times. One time my devices page was accessible but individual device pages weren't. Another time dashboards had no devices authorized.
