(internal mirror cache) Unable to locate package apt-transport-https

[perber]

In order to communicate internally with the artifactory (which we use as a mirror cache),
the package apt-transport-https is needed in the image.
(Communication with the Artifactory is carried out internally via HTTPS).

When trying to install new packages, we ran into the following problem:

E: Unable to locate package apt-transport-https

No apt-get update can be performed because the package apt-transport-https is missing.

We have now created a workaround by pulling the package via our proxy.
In my opinion, this should not be necessary.

Here you can find the Docker image as we currently have it configured. (Proxy is also added to the example.)
