I am trying to upgrade my nextcloud installation from version 13 to version 14 using the stable channel and I found this error:
root@nasone:/var/www/nextcloud# su -c './occ upgrade --no-interaction' www-data
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

An unhandled exception has been thrown:

In the log I read this message:
{"reqId":"1On5USK3nbLTbkD5Mhwa","level":1,"time":"2018-10-17T07:51:36+00:00","remoteAddr":"","user":"--"\,"app":"updater","method":"","url":"--","message":"\\OC\\Updater::checkAppStoreAppBefore: Checking for u\pdate of app \"cloud_federation_api\" in appstore","userAgent":"--","version":"13.0.4.0"}
The same error I found before for other applications, like activity, bookmarks and other; I disabled these applications and I could continue the upgrade but I cannot disable cloud_federation_api so the upgrade stopped.
