Error: Failed to execute "apt-get update"

Where is the mistake in my system and what will be the solution?

Your Kopano license has expired; therefore you don’t have access to Kopano’s own repositories anymore. Get a new license or deactivate Kopano’s own repositories.

Many thanks for your quick solution.

Setting the entries in kopano/repo for core, webapp, files, mdm and smime to false was the solution. These errors still resulted from the problems with misrepresentations of mails under iOS at the end of 2018.
