ant debian and derivatives don't work

While trying to make docker build work again, I figured building a .deb and installing it would be the easiest way to get a docker image, however ant debian, ant buster and ant bionic don't work.

I created a gitlab CI jobs and the results with the errors can be seen on gitlab.com. The relevant commands are in an MR on gitlab (in order to get a diff and trigger the pipeline).

Relevant errors:

ant debian and ant bionic
