The update app works under “ideal” circumstances only.
And the biggest unknown here is the NC update server bandwidth availability.
So, trying the update app during the first week of a new release is a bad idea…
In short, do it from the command line and forget about the app…
some reason I have slow connection speed to NC release server so my download was timing out. not directly related to the original post, but this fixed my issue after manually uploading the zip to the download folder.
After many upgrades, I think I kind of understood why it says “Step X is currently in progress”…
and that is because… it IS in progress.
Just allow some minutes, reload the page (F5 or Ctrl+r on firefox), and proceed to the next step. At least this is what happens to me.
Just for the record, my nextcloud instances are on shared hosting (ovh).
What happens more often than not is that after the upgrade process reaches the end and I’m brought to the homepage to finish the routine, it encounters another error and I have to go to the command line and use php occ upgrade to solve. But I think this is another issue.
