I just noticed that under UCS there is an error when it comes to KOPANO during package updates.
This has probably been going on for quite a while. :(How can I enter working repositories?

Hi there,
You need to do the following:
download Key mit wget, where XXX is your serial
wget https://serial:XXX@download.kopano.io/supported/core:/final/Debian_10/Release.key apt-key add Release.key
After that it will work.
