Nextcloud Box destroys itself on update


I got an nextcloudbox and run the initialsetup. After that it told me that there is a update, which I installed with snap refresh nextcloud and snap refresh ubuntu-core.
now it wont start anymore.

It just throws:

You may use your browser or the occ upgrade command to do the upgrade
Set log level to debug
Turned on maintenance mode
Exception: Updates between multiple major versions and downgrades are unsupported.
Update failed
Maintenance mode is kept active
Reset log level

Maintenance mode disabled
ERROR: object '/usr/lib/arm-linux-gnueabihf/' from /etc/ cannot be preloaded (cannot open shared object file): ignored.
Failed to setup nextcloud

So apache won’t startup and Port 80 is not listening.
