0 I'm trying to configure Docker on an Azure VM (Ubuntu 18.04 LTS). The goal is to use Jenkins to deploy my applications to my Kubernetes cluster (following this tutorial). But when I try to build a docker image inside this VM I got 403 errors during the "RUN apt-get update". While the VM itself can access those urls, it's only during the build of the docker image that I get 403 errors.
