Calculating the changes

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade.

This can be caused by:

* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu

Looking into other threads, I look into the log files to find obsolete packages and found these two:

2018-12-06 10:54:22,048 DEBUG Obsolete: docker-ce libsystemd-daemon0

Uninstalled them and all is working now, running the upgrade.
