Can't install latest docker-ce stable package on Ubuntu 16.04 LTS

[John Naggets]

Hi,

I can't install the latest Docker CE package on my Ubuntu 16.04 LTS
because of a unmet dependecy as you can see below:

$ sudo apt-get install docker-ce=18.03.1~ce-0~ubuntu

Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 docker-ce : Depends: libseccomp2 (>= 2.3.0) but 2.2.3-3ubuntu3 is to
be installed
E: Unable to correct problems, you have held broken packages

My APT sources.list looks like that:

deb http://ch.archive.ubuntu.com/ubuntu xenial main universe
deb http://ch.archive.ubuntu.com/ubuntu/ xenial-security main universe
deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable

Any ideas what is wrong here?

Cheers,
J.
