+If you already use Nextcloud with Docker but want to upgrade to Alpine Docker Images, initially you may experience permissions errors because in Alpine Images the user with permissions for the `/var/www` folder are different.  
+So, you must change the permissions of the `/var/www` folder to be compatible with Alpine:
+
+```console
+docker exec container-name chown -R www-data:root /var/www
+```
+
+After changing the permissions, restart the container and the permission errors should disappear.
