      The same happened to me. None of the first two methods worked, so I went to force the update, after I pressed check for updates, the system looked for a couple seconds then an message was shown just like in the picture attached. And everytime I go there from now, there’s a countdown telling me when these 24 will be finished.

      The pic is not mine, I found on internet.

      Thanks in advance.
