Add a package validation job for ubuntu
Recently we added AWS download support for Copernicus, which brings libssl and libcrypto dependencies. We build the package with centos 7 , which has openSsl 1.0.2 , but ubuntu has 1.1.1, so we cannot launch startmaja on ubuntu since it does not find the correct libssl/libcrypto. This branch will fix this bug, but we propose to add one step in the gitlab-ci.yml in order to test the .run with Ubuntu 18.04.
