Just got the update notification through on a small NC 16.06 installation - first stage completed fine, but going with the web based updater option failed, with a blank page displayed after clicking on “Go back to your Nextcloud instance to finish the update”.
Going in via SSH and running sudo -u www-data php ./occ upgrade completed the upgrade successfully.
Was in a hurry to get the update done, so didn’t get a chance to check logging at the time of the fail. There’s a log entry at about the right time stamp that might be related around “Could not find resource js/config.js to load”. Happy to investigate more with guidance for log entries to look for.

Ran “sudo -u www-data php occ db:add-missing-indices”, which was successful, but same error messages after returning to web updater.
