Nextcloud server software obsolete

@alnetloc : did you forgot the @ symbol for referencing? @Manoj

As I understand the NextCloud implementation, murena did some special hardenings for better security. The flipside is a development time before a new version of NextCliud could be released on the murena server. That means the scan with F would have been bad if murena had installed a natural NextCloud server. But they did some hardening.
