When will we get an update for the nextcloud or can no we have to do it ourselves?

This location block in Nextcloud NGINX config should fix the warning

  location ~ ^/(?:updater|oc[ms]-provider)(?:$|/) {
       try_files $uri/ =404;
       index index.php;
  }

just copy and past those lines in Nextcloud NGINX config, L.106 and restart NGINX service.
The warning should disappear.
A fix is on the way but it might be nice to test it first.
