I have some trouble at Ubuntu 18.04.2 LTS - does anybody have an idea for me?

I keep on ignoring that your issue template is not complete.
I did a google search for you.
apt-mark showhold to check if your system holds back any affected packages (for whatever reason) apt-get clean && apt-get update Clean the cache of apt-get and do a friendly refresh of your sources
If this still does not help, post the result of cat /etc/apt/sources.list
Please note that this is a host issue on your end which is not bound to Zammad and likely strike you on several installations with dependencies.
